Stem Cells from Menstrual Blood?

Today's science surprise...

Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source -- menstrual blood.

Stromal stem cells - cells that are present in connective tissues - have recently been identified in endometrial tissues of the uterus. When the fresh growth of tissue and blood vessels is shed during each menstrual cycle, some cells with regenerative capabilities are present and collectable. While collecting menstrual blood stromal cells (MenSCs) directly from tissue would be invasive, retrieving them during the menstrual cycle would not be.
There's even a company that's begun menstrual blood banking!
