兔移核重构胚再程序化相关基因片段的分离与鉴定

用单个植入前胚胎mRNA差别显示方法（Single Preimplantation Embryonic mRNA Differential Display Reverse Polymerase Reaction,SPEDDRTPCR），以家兔移核重构发育至2细胞、8细胞时期的胚胎及囊胚作为起始材料。研究家兔移核重构胚再程序化相关基因的表达。获得了25个与再程序化相关的基因片段，完成了对所有片段的克隆、序列分析，其中5个反向Northern证实的片段在从MⅡ到囊胚的发育阶段中呈现特异性表达的特点。这项研究为再程序化相关基因全长的分离以及功能研究奠定了良好的基础。

Isolation and Identification of Reprogramming Genes Related to the Development of the Rabbit Reconstructed Embryos

By the method of single preimplantation embryos differential display polymerase chain reaction (SPEDDRT PCR),25 reprogramming cDNA fragments were obtained from single 2 cell,8 cell embryos and blastula. After cloning and sequencing, five of them were identified by reverse Northern and characterized with stage specific expression during reconstructed embryo development. This results will help to isolate full length reprogramming genes and study their function during embryonic development.
