One of the biggest arguments against use of embryos in stem cell research is that in order to get the cells, one would have to kill an innocent life. Those in the religious community have condemned this horrific research and urged continued use of adult stem cells since no one has to die. Scientists have moaned that the prospects of embryonic stem cell research outweighed the ethical and moral concerns people like me had.
But adult stem cells have been proven to be more effective in dealing with diseases. More the 70 disease treatments have come from adult stem cells while nothing has come from embryonic research to date.
However, the use of embryos may be a thing of the past, God-willing. According to a report in this morning’s New York Times, a new procedure has been discovered that can literally convert human skin cells into embryonic stem calls – all by adding 4 genes.
All they had to do, the scientists said, was add four genes. The genes reprogrammed the chromosomes of the skin cells, making the cells into blank slates that should be able to turn into any of the 220 cell types of the human body, be it heart, brain, blood or bone. Until now, the only way to get such human universal cells was to pluck them from a human embryo several days after fertilization, destroying the embryo in the process.
The reprogrammed skin cells may yet prove to have subtle differences from embryonic stem cells that come directly from human embryos, and the new method includes potentially risky steps, like introducing a cancer gene. But stem cell researchers say they are confident that it will not take long to perfect the method and that today’s drawbacks will prove to be temporary.
If this procedure proves scientifically solid – and it looks like it – there may never be a need to destroy life anymore in order to save it.
