How do Embryonic and Adult Stem Cells Differ?
Is it ethical to create life to harvest it as an infinite source of life saving therapeutics for the sick? Interestingly, for the foreseeable future, the embryonic solution requires more than winning that ethical debate. Scientist will also have to understand how to control its in-human differentiation into heart-like cells, for example, and prove beyond a reasonable doubt that their transplant did not lead to adverse events such as cancer five, or 10 or more years post-treatment. Whereas synergetic cells – the patient’s own stem cells generated from their blood – utilize the body’s own signaling mechanisms, migrate to the site of need, engraft and enlist other circulating repair stem cells to the repair at hand. For embryonic stem cells, other complications are evident, including the following: • Harvesting embryonic stem cells from fetal tissue destroys the donor fetus. • There are a small number of embryonic stem cells available. • Their long-term storage requirements limit their ac
