| 1 | Embryonic stem cells generated by nuclear transfer of human somatic nuclei into rabbit oocytes显示文摘To solve the problem of immune incompatibility, nuclear transplantation has been envisaged as a means to produce cells or tissues for human autologous transplantation. Here we have derived embryonic stem cells by the transfer of human somatic nuclei into rabbit oocytes. The number of blastocysts that developed from the fused nuclear transfer was comparable among nuclear donors at ages of 5, 42, 52 and 60 years, and nuclear transfer (NT) embryonic stem cells (ntES cells) were subsequently derived from each of the four age groups. These results suggest that human somatic nuclei can form ntES cells independent of the age of the donor. The derived ntES cells are human based on karyotype, isogenicity, in situ hybridization, PGR and immunocytochemistry with probes that distinguish between the various species. The ntES cells maintain the capability of sustained growth in an undifferentiated state, and form embryoid bodies, which, on further induction, give rise to cell types such as neuron and muscle, as well as mixed cell populations that express markers representative of all three germ layers. Thus, ntES cells derived from human somatic cells by NT to rabbit eggs retain phenotypes similar to those of conventional human ES cells, including the ability to undergo multilineage cellular differentiation. | YINGCHEN ZHIXuHE AILIANLIU KAIWANG WENWEIMAO JIANKINCHU YONGLU ZHENGFUFANG YINGTANGSHI QINGZHANGYANG DAYUANCHEN MINKANGWANG JINSONGLI SHAOLIANGHUANG XIANGYINKONG YAOZHOUSHI ZHIQIANGWANG JIAHuIXIA ZHIGAOLONG ZHIGANGXUE WENXIANGDING HUIZHENSHENG | 2003 | Cell Research2003，13，4： | 56 |
