Stem Cells Now Seem Easier to Make
By Joe Elia
Scientists report an approach to making stem cells that's much simpler than earlier attempts.
Reporting in two Nature papers, scientists describe stressing mouse cells with a low-pH environment and having some revert to the status of pluripotent stem cells. When these cells were injected into early mouse blastocysts, they formed tissues throughout the embryos, which matured to adult mice.
In a radio interview, one author says that experiments to test the idea with human cells are under way.
