This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.For this protocol, baboons will be artificially stimulated with drugs to produce eggs that will be collected via minimally invasive abdominal surgery (laparoscopy) or ultrasound-guided aspiration. These eggs will be fertilized in the laboratory using fresh or frozen sperm. Once fertilized, the embryos will be cultured to the early cell division stage in order to derive baboon stem cells. Some eggs may undergo transfer to create cloned embryos. These embryos will also be cultured to the early cell division stage to derive stem cells. We will also collect embryos from females after hormonal stimulation and time-mating. These embryos are collected transcervically by flushing the uterus with medium. These embryos will also be cultured and then use for stem cell derivations.We anticipate that this research will enable us to optimize methods for the derivation of baboon embryonic stem cells. Any established lines will undergo rigorous testing to determine their potency and normalcy. While human embryonic stem cells may have incredible therapeutic value for treating a wide range of disorders such as Parkinson's diabetes, autism, heart disease, Alzheimer's etc., rigorous testing in animal models is necessary before any such trials can begin. Baboons provide a valuable non-human primate model in which to determine the safety and efficacy of immune-matched stem cells. SNPRC is supplying baboons for this project.
