I wonder if those who have been so rabidly attacking Rush Limbaugh over the last 24 hours will attack Mary Davenport as well:

The popular and appealing actor Michael J. Fox has taken to the airwaves in Senate battleground states Missouri, Maryland, and New Jersey with a highly misleading ad urging defeat of Republican Senatorial candidates opposing the use of taxpayer dollars to fund new embryonic stem cell line research. He states,

"Stem cell research offers hope to millions of Americans with diseases like diabetes, Alzheimer's and Parkinson's.... But George Bush and Michael Steele would put limits on the most promising stem cell research."

Mr. Fox and his ads' sponsors are guilty of conflating embryonic stem cell research, which the GOP candidates and many Americans oppose for destroying a human life in the name of curing other people's diseases, with stem cell research in general, which includes adult stem cell research and umbilical cord blood stem cell research.

...The plain fact is that embryonic stem cell research is proving to be a bust. There are currently 72 therapies showing human benefits using adult stem cells and zero using embryonic stem cells. Scientifically-minded readers can review this medical journal article on the status of adult stem cell research. Adult stem cell therapies are already being advertised and promoted while no such treatments are even remotely in prospect for embryonic stem cell research.

The fact is that adult stem cells have already produced remarkable cures, whereas embryonic stem cells have failed. This should come as no great surprise to anyone with a background in high school biology. When an embryo is created by the union of the sperm and egg, the cells begin to divide, creating embryonic stem cells from which all future tissues and organs are derived. Within days, the embryonic cells differentiate into three cell layers - ectoderm, mesoderm and endoderm. Cells in these layers continue to differentiate into tissues and organs. As the embryo matures into a fetus, child, and adult, some undifferentiated cells of the three types remain in various tissues such as bone marrow, fat, skin and olfactory tissue.
