More Science news...a new easy to harvest source of stem cells

According to ABC News, Menstrual blood yields stem cells.

Japanese researchers have harvested stem cells from human menstrual blood, a medical conference has heard.

The researchers say these stem cells could be coaxed into forming specialised heart cells, which might one-day be used to treat failing or damaged hearts.

They were able to obtain about 30 times more stem cells from menstrual blood than from bone marrow, Miyoshi says.

The stem cells were then cultured in a way to induce them to become heart cells.

After five days about half of the cells contracted "spontaneously, rhythmical and synchronously, suggesting the presence of electrical communication" between the cells, Miyoshi says.

That is to say, they behaved like heart cells.
