Amniotic fluid may be a new source of stem cells

For the first time, scientists have shown that amniotic fluid (the protective liquid surrounding an embryo) may be a potential new source of stem cells for therapeutic applications. The study was prepublished online on February 12, 2009, in Blood, the official journal of the American Society of Hematology.
