Summary;
New Scientist reports researchers have discovered adult stem cells in menstrual blood that may be able to turn into different human cell types:
"Recent research has indicated that the uterine lining, or endometrium, is a rich source of adult stem cells. But retrieving those cells is as invasive as harvesting adult stem cells from other sources, such as bone marrow. Now two separate groups say they have found these endometrial stem cells in menstrual blood. Both groups say the cells in question show all the hallmarks of stem cells: they replicate themselves without differentiating, they can be made to differentiate into many different cell types under the right conditions, and they show characteristic cell surfaces of stem cells."
