New Stem Cell Reservoir Found in Blood, News in Science
 









Excerpts: A new type of stem cell in white blood cells has been discovered by
U.S. researchers, opening up potential alternatives to embryonic stem cells for
treatment of transplant patients.  Adult stem cells are known to lurk in the
marrow of bones where blood is made. In this latest work, Dr Eliezer Huberman, a
molecular biologist at the Argonne National Laboratory in Chicago, tried to
identify blood cells that might be able to act like stem cells.  They studied
adult monocytes, a type of white blood cell. Using a series of growth factors,
they were able to make the monocytes convert into a range of different types:
epithelial cells, neuronal cells, liver cells, T lymphocytes and mature
macrophages.
