Stem Cells
Almost all life forms have stem cells in them and the main purpose of these cells is that through the process of mitosis they can divide into other various kinds of cells as well as into other stem cells. In animals there are 2 kinds of stem cells:
Embryonic stem cells and
Adult stem cells.
The embryonic stem cells are the ones that are completely unattached from the blastocyst's inner cell mass and these cells are of great importance for a developing embryo and these are known as the pluripotent cells but these cells also play a great role in the normal return of the regenerative organs like blood, intestinal tissues and skin. Whereas, when it comes to the adult organisms these stem cells work as the replenishment system for the body as it refreshes the adult tissues and for this reason they are said to have a progenitor nature (Tuch, 2006).
Mainly there are three ways through which the stem cells can be extracted from a person's body:
1. From the adipose tissues, here the stem cells are extracted through liposuction.
3. Through the process of pheresis the stem cells are extracted from the blood of the donor with the help of a machine and then the rest of the blood is returned to the body of the donor (Tuch, 2006).
Now the plastic stem cells are being used in the medical therapies on a regular basis such as in the bone marrow transplant. These stem cells are also now being produced artificially in the medical labs where they are differentiated and specialized into cells of various regions such as the nerve cell, muscles etc. The autologous embryonic cells along with the embryonic cell lines which are being created through the therapeutic cloning are said to have very promising future in the upcoming therapies (Tuch, 2006).
It is very strongly believed by the medical researchers that the stem cell therapies have the tendency to change the treatment of human diseases to a large extent. There are still many diseases that are being…
Stem Cell Research The Legal Argument and Analysis for Stem Cell Research Stem cell research is a new field of research that brings many ethical issues and considerations in which U.S. regulations have been mostly hostile while around the world, the response toward the research has been positive. What is the legal culture in which the U.S. finds itself regarding stem cell research? What are the ethical considerations involving our participation in
Conclusion This Technology Should Be Regulated and Controlled by Government There is not really much argument that stem cell research, regardless of its origin as embryonic or otherwise should be controlled to some degree by the government as the development of this research demonstrates a potential for abuse that is startling and could essentially be highly abused. The abuse of this type of research would likely be sourced in the desire of
Stem Cells Hello, my friend. I am truly sorry and sympathize as much as I can regarding your traumatic car accident and subsequent spinal injury. I appreciate that you have kept me abreast of your treatment options. Your team of physicians agree that you would be a fine candidate for treatment specifically with stem cells. Most people have heard of stem cells and are aware of the scientific and ethical
Therapeutic Use of Embryonic Stem Cells in Humans Moral issues relating to the therapeutic use of embrionic stem cells in humans Moral issues relating to the therapeutic use of embryonic stem cells in humans The inception of the idea of research of stem cells became plausible in several decades, in the past. Additionally, the research caused an ensuing countless debates to accompany the issue. In considering the research on the stem cell, several
CHIMERASChimerasContinued research on human embryonic stem cells leads to formation of more chimeras. The National Academy of Sciences has laid a common ground for ethical research on human embryonic stem cells. Wade (2015) defines chimeras as �creatures composed of more than one kind of cell� (par 1). In this essay, I will express my thoughts on why chimeras are weird to many and also why they may be of importance
Stem cells are cells that can develop into other forms of cells; Evans's cells could develop into entire mice. Evans eventually began altering the genetic material in the stem cells, creating mice that had genetic material from other creatures and could pass that material on to their offspring" (313). These findings, together with the research conducted separately by Capecchi and Smithies, enabled several teams of researchers to develop knockout
