Potential Stem Cell Source in Placentas?
WASHINGTON – Scientists looking for easier and less-controversial alternatives to stem cells from human embryos said Friday they found a potential source in placentas saved during childbirth.
They described primitive cells found in a part of the placenta called the amnion, which they coaxed into forming a variety of cell types and which look very similar to sought-after embryonic stem cells.
With 4 million children born in the United States each year, placentas could provide a ready source of the cells, the team at the University of Pittsburgh said.
