This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To initiate pilot studies on the differentiation potential of rhesus macaque embryonic stem cells into hematopoietic stem cells. Hematopoietic stem cells (HSCs) have been used in bone marrow transplantation for treatment of a variety of hematological malignancies for the last two decades. One of the major problems in HSC transplantation is lack of suitable HSC donors. Embryonic stem cells (ESCs) have been proposed as a potentially novel source of HSCs in the future. Nonhuman primates have been proven to be invaluable as a preclinical model for HSC transplantation research. We are planning to develop in vitro and in vivo models of differentiation of rhesus ESCs into HSCs. We are currently at the in vitro phase of our studies. We are receiving peripheral blood and bone marrows samples from rhesus animals through WNRPC and use them as controls and for optimization studies. This research used WNPRC Stem Cell Resources and Animal Services.
