DERIVING OOCYTES FROM EMBRYONIC STEM CELLS (ESCS)

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 本提案的目的是评估猴多能干细胞对雌性生殖细胞谱系的贡献潜力，并探索获得适用于辅助生殖技术的功能性卵母细胞的可行性。 我们的主要假设是，灵长类动物多能干细胞来源于受精胚胎，通过体细胞核移植或直接重编程（iPS）方法进行实验性重编程，能够在自发或定向分化后形成雌性生殖细胞和配子。我们在生殖细胞特异性启动子OCT 4和VASA的控制下产生GFP敲入的猴ESC系。这些细胞系应有助于在胚胎干细胞分化过程中鉴定生殖细胞。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The goal of this proposal is to evaluate the potential of monkey pluripotent stem cells to contribute to the female germ cell lineage, and to explore the feasibility of deriving functional oocytes suitable for use in assisted reproductive technologies. Our main hypothesis is that primate pluripotent stem cells derived from fertilized embryos, experimentally reprogrammed by somatic cell nuclear transfer or direct reprogramming (iPS) approaches are capable of forming female germ cells and gametes upon spontaneous or directed differentiation. We produced GFP knock-in monkey ESC line under the control of germ cell specific promoters: OCT4 and VASA. These cell lines should aid in identification of germ cells during differentiation of ESCs.
