Should the U.S. government support the creation of new lines of embryonic stem cells?
The answer to that question is not simple. The rancorous US debate about embryonic stem cells bespeaks a healthy society with genuine concern about each and every member, the tiniest and the sickest. Everyone, on both sides of the debate, wants to do what’s right.
But what is “right?”
Should frozen embryos “left-over” in fertility clinics be “sacrificed” to create stem cells to treat heart failure, autoimmune diseases, diabetes, osteoporosis, cancer, Alzheimer’s disease, Parkinson’s disease, spinal cord injuries, and birth defects?
The answer is not necessarily.
Embryonic stem cells from “left-over” frozen embryos are just one example of pluripotent stem cells (pluripotent: the potential to develop into all body tissues). Embryonic stem cells have been important model systems for research, but they will have the same tissue compatibility problems as other transplanted organs.Read More›
