Essays on Cell Research

Stem Cell Research has brought to mankind remarkable results. The use of non-embryonic stem cells have brought a particular recent success to many people. Research at Northwestern University in Chicago, Illinois, headed by a Dr. Richard Burt, has produced a procedure utilizing cells that come from the patient that has been successful in the cases that have undergone treatment. The process is known as Autologous Hermatopoietic Stem Cell Transplant (AHSCT) that has currently been used on patients who have the most common form of Multiple Sclerosis (MS Unites, 2016). The procedure uses the body’s stem cells from the ...

INTRODUCTION

Stem Cell research is one of the most heatedly debated topics in the United States. Stem cells may have capabilities that would seem like science fiction for many people. Most people have heard the term “stem cell,” but many are not exactly sure what they are. A stem cell is defined as relatively undifferentiated cells that will divide creating at least one daughter cell of the two retain the undifferentiated characteristics. This process of self renewal allows for to a number of cells that can be differentiated into whatever cells one may need; for example if a patient has ...

Despite the relative lack of information on the future implications of stem-cell therapies, research has sped ahead (Daley, et al. 793). As an example of the rapid pace of research, the International Society for Stem Cell Research, arguably the biggest international professional organization involved in stem cell research, has been obliged to update its guidelines three times in ten years (Daley, et al. 787). The purpose of this paper is to present some of the controversies evoked by stem cell research and therapies. One of the reasons given for the rapid uptake of stem cell therapies is the appeal ...

Stem cell research and therapy are not new and continue to be a controversial topic. The benefits of stem cells, and what most scientists agree are the potential benefits of stem cells, in curing disease and regenerating tissue are seemingly limitless. In the past bone marrow transplants were the primary method used to obtain stem cells for research into cures for contemporary diseases such as cancer, heart disease, Parkinson’s, Alzheimers, multiple sclerosis, and diabetes as well as spinal cord injuries. However, Embryonic Stem Cell Research (ESCR) is much more controversial. There has been a recent shift to use ...

INTRODUCTION

What is science exactly? The most generalized definition might be the pursuit of knowledge that can be studied, that can be tested through tangible experiments and then can be proven through repetition and presented in real world parameters. Science considers all possibilities but it does not necessarily answer to religious ideologies and philosophical principles that many adhere to, because science only supports what can be proven to be factual. Science, in all of its facets, has been and remains often controversial discipline, whether it is chemistry, robotics or genetics. The source of this consistent public criticisms and questioning of ...

Doctrine of Utilitarianism and Stem Cells

The use of stem cells has been a hotbed of debate for many years. Lawmakers, philosophers, theologians, scientists, and physicians all have their reasons as to whether or not we should or should not pursue the use of stem cells, as well as pursue stem cell research. We should, of course, continue to research stem cells and use them in any way that can manufacture better lives for humans based on simply on the Doctrine of Utilitarianism. Most of the controversy surrounding stem cell research and the use of stem cells surrounds morality. However, the Doctrine of Utilitarianism puts ...

ANSWER TO QUESTION 1

Introduction Biotechnology is an innovative field where biological processes are applied for the provision of genetic manipulation for microorganisms for the production and commercialisation of antibiotics and hormones amongst others. Biotechnology is a process whereby scientists use various aspects of technology to modify genes and microorganisms of living things in order to attain specific goals in the organism in which it is done. The preliminary elements of this course has shown that biotechnology is carried out in both applied and pure research. In applied research, biotechnology is used for the provision of various solutions like medicines, treatment for incurable ...

The First Amendment evinces the framer’s intent to create a “wall of separation” between church and state. The First Amendment provides that “Congress shall make no law respecting an establishment of religion” (United States Constitution, amend, I). While there can be no government establishment of religion, religion and politics have long been closely enmeshed. Since the inception of the nation, prayer has played a prominent role in government ceremonies (Lee v. Weisman 633). Beginning with George Washington, all presidents taking the oath of office conclude with the words, “So help me God” (Jonassen 861). Presidents and politicians alike ...

Philosophy and Ethics

Research and development are meant to make human lives better, they are driven by human nature of striving to make the best of available resources. Many governments in developing nations as well as in developed ones invest heavily in research methodologies. A number of drivers of most research and development are mostly related to patent protection and the exclusivity of the research rights. Patent rights need improvement from time to time. This improvement results to changes and thus more and more research being carried out. Additionally, human capital and industry structure facilitate the drive to invest more in R&D. ...

1. New born screening tests are to detect a newborn baby for different diseases and disorders that might be knowable at the time of the birth. I agree with this practice. The argument against it is that it might taint the babies life since from day 1 the parents will be aware of serious complications. I think this can easily be compared to buying a car. You would want to know what issues you face in the purchase of it.

2. Cloning in biology is when two different animals share the same DNA. So far there has not been huge ...

INTRODUCTION:

The stem cell research has been debated ever since the birth of it. However, the categorization of the stem cell research has been defined in a wrong manner. Moreover, the media is sensationalizing the topic. This has resulted in a wrong notion that all stem cell research is unethical. This is a wrong notion of the research because there are two types of stem cell research. The adult stem cell research is ethical than the embryonic stem cell research. Adult stem cell research refers to the usage of matured cells from mature adult human being without killing the host. On the ...

Introduction:

Stem Cell Research has been one of the most controversial breakthroughs of science since the late 1990’s. The extraction of the human embryonic cell on that decade has made various responses in the medical field. This has opened many doors for many scientists that are highly interested in regenerative medicine. Additionally, this has also opened new debates about the ethics of the process of harvesting stem cells. There are two types of stem cell research. The first one is known as the embryonic stem cell research. The second one is named as the adult stem cell research (Shapiro, ...

Human embryo stem cell research is an emerging field in medical science which has raised serious ethical issues. It is still a matter of debate whether or not this technique should be employed for the research purpose and what would be the end result of the embryo. Since the research process has advanced a lot, the prime focus at the present time is not to decide whether or not it should be done but to determine ways to maintain the privacy. The government looked into the matter of human stem cell research because those derived from animal sources had potential ...

Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Since ...

In the recent case brought up on appeal, U.S.A. vs Regenerative Sciences LLC, the Appellate Court re-examined the issue of whether federal laws regulating the manufacture and labeling of drugs and biological products were violated by a company that produced a mixture of stem cells and antibiotic doxycycline. In an earlier ruling, the District Court held that Regenerative Sciences LLC did violate these laws, and the Appellate Court affirmed the lower court’s judgment. This case received a lot of publicity due to the ethical issues surrounding stem cell research and resulting impacts to stakeholders affected by the outcome. The case presents ...

Science is a mathematical and results based discipline. Methodical and analytical, the expectation is that science ought to be free of bias and undue influences, unlike other disciplines. However, like any other discipline conducted by humans various factors somehow manage to influence Science. The influencing factors include racial bias and politics that provide the primary focus and subject of this paper. Racial bias is simply the attitudes, especially the negative attitudes that people may have regarding a certain race. Politics, on the other hand, in this paper applies to its broad interpretation of the practice of influencing people whether on an ...

Introduction Embryonic scientific research offers optimism for innovative therapies, but their research has always been debated. Various countries regulate such research in different ways as the subject still carries a divided opinion. What makes the topic of use of embryos so tricky to resolve, and is it so tough to resolve the issues? The research use of human embryos is currently a high ethical and political agenda in many countries. Despite the possible benefit of the research, their use is contentious because they are derived from early embryos. In this essay, some of the ethical issues surrounding the use of human ...

Healing the Future

INTRODUCTION In a diverse nation like the United States there are many ideologies, philosophies, cultural “norms,” and belief systems, it is not really surprising that people are not always going to agree. There are many legal, political, and social issues that raise ethical questions that the public cannot agree upon how best to approach and address the debated issues. One of the most heatedly debated issues that exist today is the concerns surrounding stem cell research. Stem cell research has the potential to change the field of medicine and how people are healed. However, all of that potential is ...

Human Embryos in Stem Cell Research

The controversy of the use of the human embryo in experimental research centers on the ontological and moral status of the fetus (King et al., 2009; Tauer, 2004). There is no consensus among social, medical, judicial or philosophical bodies to objectively state when the human embryo begins to be recognized as a person and a bearer to moral rights (Johnson, 2004). Even more debatable is the deliberate creation of embryos, such as through cloning, for research purposes and especially for the purpose of acquiring stem cells. The author believes that this is unjustified because it can lead to the treatment of ...

Introduction

Stem cell research has brought remarkable potential in cell growth in early life and growth. Stem cell offers the potential of addressing certain problems that humans face. The understanding of basic mechanisms of stem cell research aids human development and differentiation. Such an approach is vital in the treatment of diseases such as diabetes, spinal cord injury and other terminal illnesses (Lo and Parham, 2009). The stem cells research has generated many ethical research issues. Ethical debates on stem cell research continue to dominate the political scene. One of the major issues relating to informed consent touches on ...

‘Stem cells’ is one of the widely discussed topics in recent years. Scientific progress led to the understanding the mechanism of stem cells and their use in therapeutic applications, which involve the treatment of cancer, diseases related to heart, brain and many others . Stem cells are a distinct type of cells, which are capable of regenerating themselves through the process of cell division. Under experimental conditions, stem cells have the ability to transform into tissue-specific or organ-specific cells. Since stem cells are unspecialized cells, they are capable of producing specialized cells through the process of differentiation . While embryonic stem cells ...

According to the U.S. Department of Health and Human Services, about 18 people die every day waiting for a new organ transplant. It is currently illegal in the United States for anyone to sell their organs or tissue on the open market. It is time to change this policy not only for the benefit of organ and tissue recipients but for organ and tissue donors. Currently, most organ donations in America are from recently deceased persons who enrolled in a local or state organ donation program when they were still alive. This is not exactly a popular option for organ donation ...

Parenthood is an important period in the life of any family and avoiding mistakes on that path is crucial for creating a cohesive family unit. Sometimes, the unexpected happens and the couple is waiting for a child, even though it was not planned. For many of them, it causes frustration and determination to change it so that the carefully laid plans they had before are not ruined. However, the morality is in question. There are varying points of view regarding this idea. There are many clashes nowadays between the supporters of pro-life and pro-choice stances on abortion. The pro-life ideas ...

(Author’s Full Name)

The field of science and technology is ever-changing and continuously evolving. New discoveries and inventions are being devised by the minute. Old discoveries are revised, edited, deleted and updated. Scientists are working all across the world to improve the lives of people by experimenting with different drugs, medicines and technologies, as well as, using organic materials. Their particular focus over the past 50 years has been on stem cell technology. The concept of stem cells dates back to the early 1900s. However, detailed experimentation and examination of stem cells started in the United States ...

Stem cells can be referred to as undifferentiated biological cells, which can form specialized cell when they differentiate and have the ability to divide to form more stem cells. Research scientists have discovered a number of potential applications of the stem cells. For instance, mesenchymal stem cells are presently being tried as a potential treatment for graft versus host disease as well as graft rejection. This is after trials on a number of animals demonstrating that treatments with allogenic stem cell were not rejected and demonstrated no difference in capabilities to heal as compared to autologous stem cells. This possibility is under ...

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and further divide through the process of mitosis to produce more cells. Stem cells are found in multicellular organisms; however, in mammals there are two broad categories adult stem cells that are found in diverse tissues, and embryonic stem cells that are isolated from the inner cell mass of the blastocyst. Stem cells and progenitor cells act as a system that repairs the body in case it is injured as well as replenishing tissues (Humber 105). However, in the developing embryo stems cells differentiate into specialized cells that ...

Abstract

This paper describes and discusses the various types of human stem cells, including those in early-stage embryos (the blastocyst) and those present in adult tissue, explaining the practical uses of the various types in the medical field, where stem cells can be used to repair damaged tissue and organs. Although the adult stem cell types offer fewer possibilities for medical applications than the embryonic type, their use is less ethically controversial because it does not require destruction of a living albeit very early stage embryo. Research into stem cell applications is finding improved techniques. These include the treatment of acute ...

Embryonic stem cells have the tendency to divide for long duration and continue to have their capacity to make all cell types within the organism. Thus they are termed pluripotent stem cells. Embryonic stem cells are obtained from embryos which are particularly obtained from eggs that have been fertilized in vitro. The embryonic stem cells are recognized by two distinctive properties – their pluripotency and their ability to replicate indefinitely. Cell culture is a procedure wherein the embryonic stem cells are grown inside the laboratory. The human embryonic stem cells are first separated by removing the inner cell mass into ...

Introduction:

The morality of genetic research can play out in many ways. Two broad fields of concern are that of genetically engineered organisms and the ethics involved in the use of human stem cells taken from zygotes and human embryos. Another issue is the patenting of the genome and how that affects medicines and the rights of people to “own” their own cells. Of special concern is that bio-engineering might escape and have long term adverse effects as the manipulated creations cross genetic structures with other biological elements in the environment. This paper will look at the general ethical concerns ...

Introduction

Stem cells refer to a group of undifferentiated cells that have the potential to develop or renew into different cell types. These cells come from two main sources, that is, the adult stem cells and embryonic stem cells. On the other hand, stem cell research focuses on scientific developments, scientists are taking to restore, reshape or grow cells. Stem cell research is a topic that generates debate in many places because it involves the use of science on cells. Some people consider this research as morally wrong while others important. This paper will critically evaluate both sides of the controversy. Moreover, ...

Stem cells have a major role in the biological processes. Because of the ability of the stem cells to divide, they are important in the development of an organism and repair of damaged tissues. Stem cells have the potential to treat degenerative diseases like diabetes, Parkinson’s and heart disease. The unique characteristics of stem cells include its ability to divide, replicate and renew themselves for long periods. They are unspecialized; thus, they can produce specialized cell types. They can differentiate into other cells. Stem cells have regenerative abilities which make it useful in therapeutic interventions. They can produce ...

According to the Merriam-Webster dictionary, stem cell is an undifferentiated cell that can generate other cells which makes up specialized organs and tissues in living organisms. Stem cells are of two major types namely; adult stem cells and embryonic stem cells. Embryonic stem cells are found inside an embryo that is in its earliest developmental stage i.e. blastocyst, these stem cells eventually give rise to the adult organisms. The adult cells helps in the regeneration of worn out tissues and are located in some of the tissues in the body of living things e.g. the intestine lining, the skin’ ...

Introduction

Annotated bibliography Over the years there has been unending debate of whether the state should use federal funding to support the field of stem cell research or whether stem cell research should be allowed at all. According to Goodwin, This debate which has been looming on for centuries brings our thinking to the ethical question of biotechnological research and the moral use of human organs – the basic fundamental cells of life such as the stem cell. Those supporting the research and even those corporations funding it have proposed their support throwing weight on the fact that unused frozen ...

Abstract

The Democratic Party and the Republican Party are the two major wings of the political phenomenon in one of the world’s oldest democracy, the United States of America. Democrats and Republicans came together on doctrines of completely different ideologies and therefore their take on issues have always remained different, though agreements have occurred on small scale now and then. This article is a discussion of differences and rarer similarities between these two wings and the differences amongst factions within.

In the 1997 hard-sci-fi picture Gattaca, directed by Andrew Niccol, a biopunk utopian society has been created in the future where people have the ability to be genetically engineered from birth – as one fertility expert explains to the parents of the main character, “It’s still you, justthe best of you.” Vincent (Ethan Hawke) is an “invalid,” someone who was not genetically perfected in vitro, and so is discriminated against by employers who would prefer to hedge their bets on more ideal candidates. Despite this, or perhaps because of this discrimination, Vincent wants to leave Earth and go to Titan, ...

PROPOSITION 71 - CALIFORNIA STEM CELL

Introduction Proposition 71 refers to the 2004 law that was passed by the people of California to permit the conduct of research on stem cells in the state (Baker, 2004). This proposition followed several years of the former United States President George Bush’s administration, which had prohibited the conduct of research on stem cells in California. Consequently, the law brought dissimilar changes to both the constitution of the state of California as well as the fitness and safety regulations of the state. Most importantly, the act has been codified in the Californian constitution as article xxxv (Baker, ...

Few issues today raise as much heated emotion as the subject of eugenics and bioengineering. Hardly a day goes by when we do not see Congressional hearings on the ethics of stem cell research or debate in the media over some proposal to expand to boundaries of our artificial reproductive technologies. Hollywood and popular culture constantly bombard us with scenarios related to genetic engineering. Aldous Huxley’s controversial book Brave New World introduced the possibility of selective breeding of human beings as far back as 1932 (Huxley, 1932). More recently in 1970, the book Future Shock by Alvin Toffler portrayed ...

Stem cells is biologically fundamental structures found in all multi cellular organisms. These cells divide through the process of mitosis. Moreover, they possess a characteristic of dividing into more specialized cells and can also form more stem cells. Mammals possess two main types of stem cells. These include the progenitor cells and the embryonic stem cells. Another fundamental category of the stem cells includes the adult stem cells. All these kinds of stem cells possess specific kinds of characteristics and functions. The progenitor cells as well as the adult cells provide a repairing function in the bodies of adults. In addition, ...

During the last part of the 20th century, the science community began to do things that only a few years before would have been unimaginable. Since 1981 when embryonic stem cells were first isolated from mouse embryos research in molecular biology involving embryonic stems cells has moved quickly, and just as quickly ethic concerned having a background in Christian religious doctrine has fueled a strongly polarized debate as to whether or not such research is ethical. Research in this area has led to accomplishments such as cloned sheep and offers a novel way to treat disease. Previously in the United States there ...

INTRODUCTION

The human body consists of tissues and organs that contain over 200 different cell types.1 these cells carry out all the functions required for viability and reproduction. It was argued long ago, that in some tissues, the differentiated cells have a shorter life span and that they are not able to self -renew.2 This led to the notion that such tissues are maintained by cells that have an extensive renewal capacity, and the ability to differentiate and generate daughter cells. These cells were termed as ‘stem cells”.2 Stem cells generate only the differentiated lineages of the tissues they reside in, ...

In the field of medicine, embryonic stem cell research is a major breakthrough which gives new hope for patients with chronic illnesses and a promise for a better life for long-suffering patients. However, the debate continues as to whether embryonic stem cell research is morally acceptable. The debate is centered on two moral principles. One is “the duty to prevent or alleviate suffering” and the other is “the duty to respect the value of human life”. There are several reasons why one does not believe that embryonic stem cell research is ethically acceptable. First, in order to obtain an embryonic stem ...

Ethics of Stem Cell Research

Stem cells are central to newly developed therapies for curing degenerative diseases in humans. This is attributed to a very attractive feature of stem cells: their ability to produce a wide variety of other types of cells. Starting from stem cells, it is possible therefore to produce blood, brain, liver, muscle or essentially any type of specialized cell in a process called differentiation. Accordingly, with these therapies is now possible to aspire to find solutions to conditions that require organ or tissue replacement with a reduced rejection probability or even immune response (Juengst E). Patients with conditions like cirrhosis, muscle paralysis, corneal deterioration, ...

Stem Cell Research and Ethical Thinking

There has been a lot of debate surrounding embryonic stem cell research for quite a long time. The progress of stem cell science has slowed down because of the controversy. The main issues that have tormented the progress of stem cell research have been addressed and the ethical fault lines that will probably continue have been identified in the article “Update: Stem-Cell Research” ("Update: Stem-cell research," 2007). Although the restrictions on federal funding for embryonic stem cell research have been removed by President Obama, this article takes a look back and explores the factors that led President Bush to “ban all federal ...

Cloning is a scientific advancement that has the possibility of changing human lives for the better. Today, the world is faced with several medical hurdles to a point that avoiding the concept of cloning would be the proverbial ‘burying our heads in the sand’. This research will seek to illustrate medical and clinical applications of cloning that have immense medical benefit to human beings. The hypothesis that human cloning has medical benefits to mankind will be illustrated in several broad contexts. The first context that the research will examine is reproductive cloning. In 1997, the scientific world witnessed a milestone after ...

Abstract:

Medicine and science had always maintained a steady flow of debates by the beginning of the 20th century with the ongoing increase of diseases, and virus mutations keeping up with the modern technology. Medicines had to be updated regularly to ensure that mutations would not influence a person’s sickness and overall health. It is common to see various medical procedures claiming that they can cure a disease or complication without the need to pay medicines regularly. One of these offerings is known as stem cell treatment, which uses stem cells to repair damage tissues or cure diseases. While the preliminary studies ...

Stem cell research

Stem Cell Research

Stem cells comprise natural in the human body capable of differentiating into different specialized cells (Cummings, 2009). These cells are also capable of self-renewal whereby they reproduce into more stem cells. Mammals produce two types; adult and embryonic stem cells. Embryonic stem cells are harvested from the inner cell mass of embryos in the blastocyst stage. Embryo cells differentiate into all the organs and tissues that form the human body. Adult stem cells are present in various tissues within the body (Cummings, 2009). These cells are responsible for body repairs and replenishment.

Stem Cell Research

Stem cells are possess the ability to develop into different cell types in the body. They can also serve as a repair mechanism, dividing several times to replenish damage tissue. Stem cells are unspecialized cells, which can renew themselves through cell division, sometimes, even after a long period of inactivity. Stem cells can also be induced, under physiologic or experimental conditions to produce tissue specific or organ specific cells (News Medical, 2012). Embryonic stem cells are stem cells derived from the early stage of division of human embryos shortly after fertilization. They are isolated from the inner cell mass of ...

Bioethics refers to the ethics in the field of medical and biological research and its application. Some of the key ethical concerns in this field are stem cell research, use of animals for human transplantation, cloning and exposing pregnant women to new drugs. With advent of new assisted reproductive technologies, custody of frozen embryos in in-vitro fertilization (IVF) has also become an ethical concern. The paper deals with three such ethical concerns pertaining to custody of frozen embryos in the event of divorce, stem cell research and use of animals for human organ transplantation. The case is about a ...

In the early stages of development, a human embryo has Pluripotential stem cells. Stem cells have the potential to dived and differentiate into specialized cell forming different body tissues and performing different functions. This coupled with their ability to self-renew gives stem cells wide applications in research and transplantation therapy. In his paper on “New potential for Human Embryonic Stem Cells”, Gearhart notes that stem cells grown in culture can be derived from either the inner masses of blastocysts (ES) or from primordial germ cells (EG). Human ES cells have been isolated and are currently the major focus of research ...

Besides the benefits from the research in stem cells, the research has proven to be one of the most controversial issues in the modern world. The prime concern is deciding whether its continuity is right or wrong. Many are arguing the issue of morality which involves the use of human embryos, genetic engineering, cloning and the biological impacts resulting from the research. It has spanned a strong debate in regard to its credibility in regard to ethical concerns primarily about creation, destruction and also the use of embryos. It does not stop there because of other issues raised about the species ...

Morality of using animal in stem cell research

Every research is guided by values and in stem cell research responsibility and sensitivity to ethical values are the guiding principles that must be adhered to. Some of the beneficiaries of the stem cell research are the Alzheimer’s disease and dementia which have become a key focus for researchers who are trying to establish how dementia affects the normal functioning of the brain. There is also evidence of Parkinson’s patients benefiting from stem cell research. Also the IVF project is a result of the stem cell research. The research is undertaken under the following scientific and ethic guidelines ...
