In bone marrow, where blood cells are born, a few cells have the unique ability to develop into any type of blood cell, as needed, and to produce offspring that can do the same.

After years of experiments failing to reveal what maintains this remarkable population of self-perpetuating cells, called hematopoietic stem cells, researchers working with mice have now discovered a way to propagate the cells in the laboratory. If the method works for human blood cells, it would...

Embryo stem cells turned to blood.(Brief Article)
Science News ; Even as the Senate began debating the topic of using stem cells from human embryos, a research team reported that it had converted the cells into all the various types of blood cells. This result takes a step toward using embryonic stem cells as a source of blood for transfusions or as an
