While embryonic stem cell research has been stymied by limited federal funding, researchers continue to look for other cell sources that offer the same promise for treating disease.To that end, Tufts University researchers now report there may be a previously unrecognized and untapped source of fetal cells in the blood of women who have been pregnant. And researchers from Yale University believe adult stem cells from bone marrow may have more potential than researchers have realized because they discovered that bone marrow cells play a role in the development of the endometrial lining of the uterus every month in women who have undergone marrow transplants.Results of both studies appear in the July 7 issue of the Journal of the American Medical Association.
