Essay on Stem Cell Controversy - 2805 Words.
The use of stem cells to replicate human tissue and organs will help to prolong lives of human beings and possible slow down the aging process by replacing our cells. The cons of stem cell research are the use of stem cells and the ethical issues associated with using embryos to harvest cells for research.
The Controversy of Stem Cell Research Essays 1410 Words 6 Pages The Controversy of Stem Cell Research One of the most controversial topics these days is Stem Cell Research. There seems to be a split opinion among societies about the research and whether it is socially and morally acceptable.
Embryonic stem cells (ES cells) are stem cells taken from the inner cell mass of the early stage embryo called a blastocyst.Human embryos reach the blastocyst stage 4-5 days after fertilization.At that time, they are made up of between 50 and 150 cells. The stem cells' state, and what the daughter cells turn into, is influenced by signals from other cells in the embryo.
Some of these stem cells have a capacity to differentiate into a limited number of different cell types, such as blood cells, muscles and neurones (i.e., they are multipotent), but they have not been shown to be pluripotent (able to differentiate into any cell-type) in the way that embryonic stem cells are.7 This limitation means that adult stem cells offer more limited potential benefits in.
The programs like Proposition 71 are stuck in to mud as they are politically debatable, speculative and controversial because the stem cells research itself is very politically controversial. Each stem cells research program remains to be highly speculative so the government should not gamble with public fund into such programs where we cannot predict the results at all.
Essay The Controversy Of Stem Cell Research. study, stem cell research. Stem cells are unspecialized cell found predominantly in embryos and adult body tissue that have the potential to take on the role of another cell. The discovery of human embryonic stem cells in the late 1990’s and paved a new road for regenerative medicine.
The reason of the controversy around stem cells is focused mainly because embryonic stem cells can only be gathered when an egg is being fertilized. The process of gathering a sample of stem cells started by triggering a human egg that has been left in cryo for more than the legal limit, to grow into an embryo like the normal growth of a child.
