ALTERED NUCLEAR TRANSFER

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 该项目的目标是利用改变后的体细胞核移植到灵长类动物的卵子中，希望在这个过程中绕过生产/销毁可存活胚胎的同时产生多能干细胞。我们发现灵长类胚胎中的滋养外胚层血统可以通过下调未受精卵母细胞中CDX2的表达而被取消。多能的内细胞谱系不受影响，并产生有功能的ES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 project is to utilize altered somatic cell nuclear transfer into primate eggs with the hope of yielding pluripotent stem cells while bypassing the production/destruction of viable embryos in the process. We showed that the trophectodermal lineage in primate embryos can be abrogated by downregulation of CDX2 in unfertilized oocytes. The pluripotent inner cell lineage was not affected and produced functional ES cells.
