| 摘 要： | 分离培养鸡胚胎干细胞(ESCs),体外培养传代后,进行碱性磷酸酶活性检测和SSEA-1染色鉴定;并用线性化的质粒pEGFP-N1转染鸡ESCs。受体种蛋经赤道面开窗后,将经转染的ESCs注射到受体鸡胚胚下腔,以便制作嵌合体鸡;对获得的嵌合体鸡分别提取血液和组织DNA后进行PCR检测。结果表明:5只存活的的嵌合体鸡血液中没有发生EGFP基因嵌合,但有4只嵌合体鸡的部分器官表达了EGFP基因,其中有2只鸡的性腺发生嵌合,表明利用赤道面开窗后对受体鸡进行胚下腔显微注射可以生产嵌合体鸡。

| Abstract: | Chicken embryonic stem cells(ESCs) were sep arated and cultured in vitro.Alkaline phosphatase activity(AKP) and SSEA-1 staining was conducted to detected ESCs.Then,chicken ESCs were transfected with linearized plasmid pEGFP-N1.The receptor eggs were drilled a window at the lateral shell of egg,then,the ESCs transfected with pEGFP-N1 was injected into chick embryo cavity so as to make chimeric chicken.The chimeric chicken was detected for both of blood and different tissue by PCR.The results showed five chimeric chicken were obtained in this study and found that four of them expressed EGFP gene in some organs,only two of them expressed EGFP gene in the gonad,indicating the chimeric chicken could be obtained through chick embryo cavity micro-injection by drilling a window at the lateral shell of egg. |
