Stem Cell
Human Embryonic Stem Cells Sources-
HESCs are derived from the inner cell mass of the human blastocysts.Blastocyst is formed five days after fertilization of the egg by the sperm. It has outer shell which matures and if survives implantation become placental tissue and the inner cell mass become the tissues of the human body
The extraction of HESCs from inner cell mass for research purpose leads to the destruction of the embryo. The major source of human embryonic stem cell tissue are the spare or supernumerary embryos created during in vitro fertilization as a part of infertility treatment.
benefit of embryonic stem cell
If you look at the benefits of Stem cell extraction is useful in many ways, such as finding new ways. In the treatment, cloning endangered species, capped. Research and advanced treatment technology to help the medical community. Is making progress even more.
But looking at the ethics of human embryonic Stem cell extraction. Researchers often use embryos that fetus was only 5-7 days after fertilization. The result of this was the cell extraction. The embryo is destroyed Not to further growth It's like killing another life.
