Human Embryonic Stem Cell Research - Essay Example

Comments (0)
The study of the Human Embryonic Stem cells has been the center of discussion in the scientific arena. It also created widespread debates all over the world not just because of how it is done but also of the moral issues surrounding it. Embryonic stem cells are pluripotent cells that could be obtained from a week old fertilized egg…

The purpose of this paper is to give a brief background on some facts about the human embryonic stem cells. Particularly it will explore answers to the following questions:
Each of us started as a single living cell that resulted from the union between a sperm and an egg. From this single cell, certain chronological events took place that eventually led to the development of different body parts. Cells increase in number and differentiated to many cell types until we reached and assumed a human form. Many doctors agree that this is a miracle of Science. On the other hand, some started to try and make this miracle happen in a petri dish for purposes of helping fertilization occur between couples wanting to have babies. Eventually, this simple experiment led to the discovery of another potential wonder that these dividing young cells could give. Thus, embryonic stem cells became a word of mouth in all scientific publications and journals. These cells are found in a 4-5 day old embryo. They have a unique capability to continuously divide that enables them to self-renew. ...
Embryonic stem cells are also capable of differentiating and developing into many cell types such as brain, heart, liver, skin cells, etc upon instructions of biological signals (NIC 2006). Hence, they are also called pluripotent cells.
History of Embryonic Stem Cell Research
Embryonic Stem Cell Research began through the efforts of Gail Martin, Matthew Kaufman and Martin Evans when they derived mouse embryonic stem cells way back in 1981 (The White House 2001). However, the breakthrough happened in February 1998 when James A. Thomson of the University of Wisconsin and his team announced that they had successfully isolated and cultured the first human stem cell line derived from blastocytes. The team obtained these blastocytes left over from successful in-vitro fertilization procedures (Stem Cells Portal 2008). Thomson revealed that the obtained cells transformed into different types when it was injected under the mice's skin. Furthermore, there were also remnants of the fundamental mammalian embryo layers proving that these cells are also flexible during the course of their development. The results obtained from the study shed hope gearing towards finding a medical treatment for some diseases (Pedersen 1999).
Just about the same time that year, another group of scientists were conducting experiments similar to that of Thomson. John D. Gearhart of Johns Hopkins University in Baltimore was also extracting and culturing the same cell types from human fetal ovaries and testes (Pedersen 1999). Other developments and laboratory experiments soon followed with the same aim of developing their own embryonic stem cell line. One major scientific development took place in May of 2003 when researchers announced that they have successfully ...Download file to see next pagesRead More

Should Stem cell research be federally funded
Although, the lines dividing opposing sides are not clear cut, the positions center around two polarized arguments. On one hand, proponents of federal funding for stem cell research cite the great potential of research findings for application to actual treatment.

Human Embryonic Stem Cell Research should be Legalised
Though bioethical views are important in influencing global opinions, the moral arguments disapproving the legalization and funding of scientific research are unsubstantiated and deceiving. After the isolation of embryonic stem cell in 1998, stem cell research scientists presumed they had found a solution to several underlying medical problems.

Casual analysis
They make use of term such as embryonic bodies, cluster of stem cells, and blob of tissue whenever they are discussing the controversial issue of embryonic stem cell research. However, use of decent terms to refer to the practice of destroying human embryos does not make the research virtuous.

Proposal essay
The research involves the removal of embryonic cells from an embryo and culturing them in the laboratory for research on human diseases (The Witherspoon Council on Ethics and the Integrity of Science 129-133). The significant capacity for stem cells to develop into different body cells forms the basis for scientists conducting this research.

Stem Cell Research - Stem cell research
Science and technology has developed so much that in the recent years scientists hope to use these cells to develop new tissues, treatments and potentially even organs for transplanting into a patient. First and foremost argument made by the scientific community is that human stem cell research is said to promise new life changing treatments and possible cures for many devastating diseases and injuries, such as Parkinson's disease, diabetes, heart disease, multiple sclerosis, burns and spinal cord injuries (Young 2-16).

Stem Cell Research from Christian Perspective
The potential benefits are not proved and refer to the future while the embryos die immediately once the stem cells are taken. This is the valid cause to state that stem cell research is ethically and morally wrong. Stem cell research is relatively new topic for discussion among the public, the scientists and believers.
