The sources of cells, however, were not human beings in a legal sense. The Johns Hopkins researchers took theirs from fetuses that had been aborted early in pregnancy. The Wisconsin group used blastocysts, clusters of about 140 cells that develop within a week after fertilization. (They were donated by couples...
Until now, though, isolating stem cells in their pristine state has proved difficult, and keeping them that way for further study next to impossible. That is why it is so remarkable that two independent teams, one at the University of Wisconsin in Madison, the other at Johns Hopkins, announced last...
The potential controversy, however, is equally tremendous. It is illegal to use federal money for research that involves human embryos--leading both the Johns Hopkins and Wisconsin groups to seek funding from Geron Corp., a biotech firm based in Menlo Park, Calif. But staying within the letter of the law...
The list goes on to include virtually any disorder that involves the loss of normal cells: stroke, muscular dystrophy, spinal-cord injury, kidney or liver disease, blindness caused by degeneration of the retina. Stem cells could also provide drug companies with a limitless supply of normal human tissues to use...
Answering all these questions and turning the answers into useful therapies is a daunting undertaking that could keep scores of scientists busy for years. Unfortunately, Geron's pockets are not bottomless, and the traditional source of funding is unavailable. In order to inoculate themselves against charges of violating a federal...
