Researchers have identified a new source of adult stem cells that could one day lead to treatments that don't require the use of controversial embryonic stem cells.
By studying mice researchers have turned early sperm cells into several types of adult stem cells.
they found cells programmed to become sperm have the ability to be reprogrammed into adult stem cells. These cells can then become any type of cell in the body – researchers were able to create heart cells, brain cells, even blood vessels.
