摘要 目的探讨人妊娠各期胎盘滋养细胞凋亡与其调控蛋白Bcl-2及Bax之间的关系。方法采用TUNEL法检测人妊娠各期胎盘滋养细胞的凋亡情况,采用免疫组织化学方法检测人妊娠各期胎盘滋养细胞层Bcl-2,Bax的表达情况。结果细胞凋亡在早、中、足月和过期妊娠4组胎盘滋养层中表达随孕期的增长逐渐增多,差异有显著性(P<0.01)。Bcl-2,Bax在4组胎盘滋养层的表达及Bax/Bcl-2值均随孕期的增长逐渐增强(P<0.05)。结论在人的整个妊娠时期中,胎盘滋养细胞凋亡与Bax/Bcl-2的比值正相关。此外,Bcl-2和Bax虽单独具有调控细胞凋亡的功能,但其相互间的比例对细胞凋亡的影响更为重要。
