摘  要:
实验旨在利用精原干细胞介导的方法体内转染融合基因EGFP-MMx,制备抗病毒性疾病转基因鸡。采用脂质体包埋法,睾丸内注射EGFP-MMx融合基因,术后采集30、40、50、60、70、80 d睾丸组织进行冰冻切片、基因组PC R、点杂交实验,转染后60 d公鸡精液人工授精于正常母鸡,对后代血液采用PC R检测技术、R T-PC R和W estern blot方法检测外源基因EGFP-MMx的整合表达情况。结果表明:睾丸基因组点杂交阳性率为72.2%。通过PC R、R T-PCR检测方法,在实验公鸡精液和F1代血液中检测到目的基因,精液阳性率为25%,F1代阳性率为10.53%,Western blot检测F1代阳性率为7.89%。结果证明外源基因通过睾丸注射法可整合到基因组上,为培育抗病转基因鸡提供参考依据。

摘  要:
In order to cultivate anti-viral transgenic chickens through transfected spermatogonial stem cell with fusion gene EGFP-MMx.After injecting fusion gene EGFP-MMx into testes,we did some testing such as frozen section,PCR and dot blot of testes' tissues of 30 d,40 d,50 d,60 d,70 d and 80 d,a few of normal hen were inseminated artificially with cock semen of 60 d.Finally we detected the integration of exogenous gene EGFP-MMx of the offspring by PCR,RT-PCR and Western Blot.Dot blot positive rate of testes genome was 72.2%.PCR and RT-PCR positive rate was 25% and 10.53%(4/38)in sperm and F1 blood genome respectively,while Western Blot positive rate of F1 blood was 7.89%(3/38).It was proved the possibility of cultivating anti-viral transgenic chickens by the method of testes injection method which can integrate foreign genes into the genome.
