...unearthed ways to derive embryonic stem cells from mice, eventually gaining the knowledge to extract them from humans, in 1998. Embryonic stem cell research is when an egg and sperm cell is obtained from a donor, mixed in a Petri dish, and the egg is fertilized to produce a stem cell line for research.The scientists begin this process by conducting in vitro fertilization, or an egg being fertilized out of the womb, and into a lab setting. A stem cell is essentially a “blank” cell, that’s capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. In this case, a host cell where the embryo can prosper and grow to be used later on for research. In humans, mice, and other mammals, the embryo is a ball of approximately one hundred cells at this stage. Although embryonic stem cell research has great potential in deciphering the cause behind puzzling disorders such as Type 1 diabetes, Parkinson's, and heart infractions,...

...Stem Cell Ethics Essay In today’s society there are many things that are deemed ethical or not unethical. Underage drinking, drug use, divorce, these are just a few that might be considered unethical. Stem Cell Research can fall into either category depending on a person’s views. A stem cell is a biological cell found in every multicellular organism that can divide into different specialized cells. In a growing embryo, stem cells help maintain the regeneration parts of organs. “Cells grown in the lab provide scientists with the opportunity to "engineer" them for use in transplantation or treatment of diseases” (National Institutes of Health). There are two different types of stem cells, embryonic and adult. Embryonic cells are in the inner cell mass and adult cells are found in tissues. “Embryonic stem cells exist only at the earliest stages of embryonic development and are capable of making any cell type in the body. Under the right conditions, these cells retain the ability to divide and make copies of them indefinitely. Scientists are beginning to understand how to make these cells develop into any of the more than 200 different types of cells in the human body” (Stem Cell Research). “Adult stem cells are more limited and specialized than embryonic stem cells. They have the ability to make just one or two kinds of tissue, such as blood and immune system cells, brain or muscle cells. Adult stem cells also have a more limited capacity to replace themselves than do embryonic...

...Stem Cell Research Essay Stem Cell research is a highly controversial topic in the world of science. Many people disagree with and oppose the research because of their belief that the research is unethical. The laws regarding the research of Stem cells vary from country to country. Many countries have very strict laws on the research and some have completely banned it. There are many organizations and scientists that are pushing for the research and study of the stem cells. These viewpoints establish that Stem cells can be very beneficial for human use. There are three main types of stem cells: embryonic, tissue and induced pluripotent (Euro Stem Cell, 2012). Embryonic stem cells are used because they do not have a designated function...

...English Argumentative Essay Should embryonic stem cell research carry on? Embryonic stem cell research creates an ethical dilemma. It forces us to choose between two moral principles: the duty to prevent or lessen the suffering; or the duty to respect the value of human life. In embryonic stem cell research, it is impossible to respect both moral principles. To get embryonic stem cells, the early embryo has to be destroyed. This means destroying a potential human life. But embryonic stem cell research could lead to the discovery of new medical treatments that would lessen the suffering of many people. So which moral principle should have the upper hand in this situation? The answer hinges on how we view the embryo. Does it have the status of a person? Some say it does, as many people think of an embryo as a fully-grown human. The reason for this is the fact that, once an egg is fertilized, unless stopped, it will grow into a fully-grown adult. This opinion is often related to religious rules which state that conception marks the beginning of human life or the presence of a soul. It has been argued that "the line at which an embryo becomes a human life remains as chance as ever". Others argue that embryos are not humans, believing that the life of Homo sapiens only begins when the heartbeat develops, which is during the 5th week of pregnancy, or when the brain begins working, which is about 54 days after conception. Embryos are of value, however they are not equivalent...

...SBI4U ISP Part II: Genetic Technology Research Paper Embryonic Stem Cell Use Abstract: Researchers discovered that embryonic stem cells could be originated from early human embryos. This discovery has raised a series of ethical and public-policy questions that are now being confronted by multiple international organizations, nations, cultures, and religious traditions. This essay surveys policies for human embryonic stem cell research in four regions of the world, reports on the recent debate at the United Nations about one type of such research, and reviews the positions that various religious traditions have adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates. There are many ways in which human stem cells can be used in research and the clinic. Studies of the medical use of Embyonic Stem cells will yield information about the complex events that occur during human development. A primary goal of this work is to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs. Scientists know that turning genes on and off is central to this process. Some of the most serious medical conditions, such as cancer and birth defects, are due to abnormal cell division and differentiation. A more complete understanding of the genetic and molecular controls of these processes may yield information about how such diseases arise and suggest new strategies...

...Maffei Stem Cell Research Essay Majority of the general population knows or has heard something in reference to stem cell research, weather it is from magazine articles or news, at some point in our daily lives we’ve heard the term “Stem Cell Research.” Stem cells due to their controversial nature, has seen numerous changes in the legislation governing its research and the types of stem cells – weather it is fetal, cord, embryonic, etc... – The legislation affecting stem cells can determine where the U.S. stands on this ground breaking research. According to Lanza, A simple definition for stem cells is as follows “a stem cell is a cell that has the potential to develop into a number of different types of cells in the body.” (2011). Basically, stem cells are the base of all organs and tissues in the human body, a master cell of some sort. Stems cell, also have the potential be the backbone of many medical breakthroughs in centuries to come, from age prevention to helping with disabilities such as blindness, inability to walk, etc... As mention earlier in this paper there are many types of stem cells, but for purpose of this paper I shall focus on adult & embryonic stem cells. An adult stem cell is an undifferentiated cell that is found amongst differentiated cells in an organ or tissue that processes the ability to renew itself, as well as differentiate into other specialized cell types. By their nature, adult stem cells aren’t as controversial as embryonic stem cells...

...Stem cells are a special type of cell located in the bodies of all multicellular animal life. They are the precursor stage of all adult cells, so are unique in their ability to develop into every other type of cell in the human body. This specialisation makes them of great interest in the field of biomedicine, as they can be utilised to replace damaged or lost cells in individuals with injuries or genetic illnesses. However, the research and usage of human stem cells remains a controversial and divisive matter. This essay will explain the main reasons why controversy surrounds their use as a medical therapy. The main controversy of stem cells being used in medicine revolves primarily around the research and usage of a particular kind of human stem cell; embryonic stem cells(ES cells). ES cells, as the name implies, are stem cells found only in the innermost mass of cells within blastocysts; the early stage of a human embryo. The extraction of these cells for use however, results in the destruction of the blastocyst. This raises issues about the morality of extracting ES cells, as they can only be removed at the cost of denying the future embryo the chance of developing into the foetal stage and subsequently, becoming a human life. One philosophical outlook on why the use of ES cells is immoral is that “...the human embryo is the same individual as the human organism at subsequent stages of development”1, a viewpoint that is relayed in the sentiments of a 2003 public...

...October 2013 Formal Essay I Stem Cell Controversy Religion and science, two forces that mix as well as oil and water. For thousands of years people have argued which side is correct: one extreme will tell you that a strong faith in God will lead to a better life, the latter extreme will tell you that life has many more complexities than just a faith a deity. These two both see life differently, the Christians think life should be cherished no matter how small or suffering. While science believes there can be something extracted from one’s small life, scientists have found, that the earliest cells of an embryo can be developed into any sort of cell. The study of this is known as stem cell research. The inner cell mass of blastocyst is extracted from the woman’s ovaries and differentiated into embryo bodies and from there they differentiate into either neuronal or pancreatic cells (bethesda). From here, it is difficult to produce enough stem cell lines or to produce the correct cell type (National Cancer Institute). This finding can save or increase many humans quality of life. But is it ethically correct? Is it morally correct? Could these findings interfere with the “circle of life”? Could this interfere with the genetic code of humans and astronomically change the world forever? Are we interfering with God’s will or the circle of life? The history of stem cell research is brief. In 1962, a new frog was produced by taking an adults frog’s intestinal cell and transporting...

...a distinct time point. To many, life begins at the time when we are born in the hospital as a baby. At that particular moment, an individual is officially declared as “born” and thus be granted an identify in the society. Seemingly, life of an individual begins at birth. However, debates on when life begins have been on-going throughout human history due to its significant ethical, biomedical and philosophical consequences. Despite the many factors we need to consider when thinking about when life begins, Dr. Ricki Lewis, a science writer with a PhD in genetics, managed to narrow down the options to 17 time points, based primarily on biomedical factors. Amongst these time points, I believe life begins at week 22 of pregnancy. In this essay, I will support my stance by comparing it to some other major arguments. The ethical implications of my stance will also be illustrated and discussed. Life begins only when an organism has the ability to survive. When we discuss when life begins, it is important to define what life is. There are three definitions of life, said Dr. Chris McKay on his article. Life can be referred to a collective understanding of a system of material entitles that can undergo evolution (i.e. when we are asking if there is any life on a planet). Life can also refer to the ability of an organism to develop and grow (i.e. is something alive). However, the definition of life that is most applicable to the discussion we are having is the last case where life...

...12 November 2010 Cloning Human, animal, and plant cloning is one of the most controversial subjects in modern science. There are many good arguments in favor of cloning, as well as many against it. In my opinion, plant and animal cloning could be very efficient to society by way of creating more food, but I also view it as unethical. In this essay I will discuss many pro’s and con’s of cloning. Cloning can help the human race in many ways, but is it necessary? One way it can help us is by the cloning of plants and animals. In doing this, we could create more food and genetically engineer the food to maximize its health. "Commercial livestock cloning could inundate the food supply with novel products that have not been safety tested."(Mendelson). Most scientists who oppose the idea claim that cloned animals usually have birth defects, and have not been properly tested for safe consumption. Although this could be true, with the rapidly advancing technology in today’s world it probably will not be long until cloning is perfected, and the animals pass all tests. However, is the cloning of animals really necessary for us to survive? Those who are on the more ethical side of the matter believe that God has and will continue to provide us with plenty of plants and animals to survive on. Thus, the argument can go back and forth depending on your beliefs and personal ethics. Ultimately the answer to the question is what you make it. Another way cloning can benefit us is by the...

...idea of it entirely. Some think that the process of human genetic engineering is a bad thing because technically it takes life. The argument is that even though life is being created through fertilization of an embryo, the life cannot feel or understand pain yet, making the process of genetic engineering justifiable. Also, study and research through genetic engineering will ultimately help those who can feel pain. This procedure will cure thousands, and thousands more will be healthier and better off because of the advances we will make. Human genetic engineering is the process of genetically engineering people by modifying or changing their genotypes before they are born. A genotype is a genetic institution of an individual with respect to a particular characteristic; for example eye or hair color. So if a person’s genotype told you they have blue eyes, you could modify that genotype to make it so they would have green eyes. The cells in a person’s body contain encoded information about the body’s growth, structure, and functioning in the form of genes. Human genetic engineering is aimed at decoding this information encrypted within the cells, and applying it for the benefit of mankind. There are two types of human genetic engineering, but the most effective kind is called Germline modification. In Germline modification, the genes in the early embryos are changed completely. Because the embryos are changed before the fertilization process, the genes are inheritable....

...degenerative diseases, thereby defective genes could be replaced and help improve the lives of millions. However, cloning in the human sense has had a difficult start. DNA cloning has permitted the development of modern biology, in particular within the last forty years. In this time frame the world has passed from theories to actually cloning genes. Subsequently, The University of Utah Health Sciences did a study on the history of cloning: Mitalipov and colleagues were the first to use somatic cell nuclear transfer to create a human embryo. …In this experiment, researchers took a skin cell from a patient and fused it with a donated egg cell. Key to the success of the experiment was the modification to the culture liquid in which the procedure was done and to the series of electrical pulses used to stimulate the egg to begin its division. Following the cloning controversy of 2004–2005, in which South Korean scientists falsely claimed to have used somatic cell nuclear transfer to create embryonic stem cell lines, the scientific community demanded much stronger evidence that the procedure had actually been successful. (Learn. Genetics) Subsequently, many states in the US began to prohibit the use of therapeutic and reproductive cloning. Regardless, cloning should be decriminalized, with the stipulation that serious regulations be put into place. People, often too caught in the moral implications of cloning never take the time to learn the scientific process. Moral implications are thoughts...

...later leads to become a spinal cord (1,2). Development of the CNS involves many complex mechanisms beginning at the onset of transformation of a single layer of ectodermal cells, the neuroectoderm until the end of the differentiation process resulting into highly complex structure involving variety of neural cell types (1,2). A large number of cell types need to be arranged spatially and temporally to form a complex structure during an embryo development. CNS being one such complex structure formed during embryonic development involves many interlinked molecular mechanisms giving rise to interlinked and diversified neuronal circuits. Although a few of the signaling pathways (like shh) have been identified causing cellular diversity in a vertebrate CNS more studies have to be done to identify the involvements of any more of such signals. (1) The nervous system (NS) develops from the ectoderm of a developing embryo. First to develop is the neural plate followed by formation of a neural groove in the neural plate very shortly. This is then followed by joining of the edges of the neural groove to form a neural tube, which later develops into the brain at the frontal part while the following part develops into the spinal cord. The left over cells on either side of neural tube midline form the neural crest cells, which constitute the peripheral nervous system. (1) The vertebrate CNS originates from neural plate that in turn generates from dorsal ectoderm of gastrula- stage embryo...
