Scientists Discover Stage At Which An Embryonic Cell Is Fated To Become A Stem Cell
Science Daily — Cambridge scientists have discovered the stage at which some of the cells of a fertilised mammalian egg are fated to develop into stem cells and why this occurs. The findings of the study, which overturn the long-held belief that cells are the same until the fourth cleavage (division) of the embryo, are reported in the journal Nature.
