摘要 目的研究携带增强型绿色荧光蛋白(EGFP)的慢病毒在活体大鼠卵巢中感染定位及表达情况。方法将携带EGFP的慢病毒注射至实验组大鼠双侧卵巢部位,另设对照组和空白对照组,每天观察大鼠一般情况;分别于注射后第7,14,21和28天处死大鼠(每个时间点每组各2只),取出双侧卵巢分别称重,行石蜡切片HE染色后光学显微镜下观察卵巢组织结构的变化和卵泡总数量;实验组卵巢行冰冻切片后在荧光显微镜下观察EG-FP的表达。结果3组大鼠一般情况及卵巢重量均无明显变化;行石蜡切片HE染色后,显微镜下见慢病毒注射的卵巢均未见明显的变性、坏死等病理形态学异常;实验组大鼠卵巢行冰冻切片后在荧光显微镜下观察,第7,14,21天EGFP的表达逐渐增强,至第28天开始稳定表达,感染效率可达90%以上。结论慢病毒载体能有效地转染活体大鼠卵巢而无明显毒不良反应。
