The Cell Processing Core offers a variety of human hematopoietic cells or other products to investigators for their research programs. The Core can provide specific cell populations such as total nucleated cells, low density mononuclear cells or CD34+ cells from bone marrow, umbilical cord blood, peripheral blood or G-CSF mobilized peripheral blood through a Normal Donor Repository. Other enriched cell populations may be available via special request. The Core can also provide unprocessed samples, plasma or serum.
