Testing is, of course, already commonplace. As many as 9 out of 10 pregnant women in the U.S. submit to some prenatal screening. Typically, this involves sampling the mother's blood--so-called serum-alpha-fetoprotein testing to seek out telltale proteins that may indicate spina bifida, neural-tube defects or Down syndrome--or looking directly at the fetus with ultrasound scans. For women over 35, doctors usually recommend more invasive procedures in which actual fetal cells are gathered from the womb's amniotic fluid (amniocentesis) or placenta (chorionic villus sampling...
...incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations. But if efforts to understand and master stem-cell development prove successful, doctors will have a therapeutic tool of incredible power...

...Wisconsin group, whose announcement appears in the current Science, went even farther. Its stem cells can evidently survive indefinitely. The researchers have also coaxed them to take the next step and differentiate into neural, gut, muscle and bone cells. "It's an important first step," says developmental biologist James Thomson, who led the Wisconsin team. National Institutes of Health director Harold Varmus pronounced the potential applications of the Wisconsin work "tremendous...
