作者在以往的研究中注意到人胎盘绒毛细胞滋养细胞 ( Langhans’细胞 )有明细胞 (多量 )与暗细胞 (少许 )之分[1] ;葡萄胎妊娠水泡的细胞滋养细胞亦有明细胞 (多 )与暗细胞 (少许 )之别[2 ] 。在应用 DNA缺口末端标记技术与电镜结合研究人妊娠滋养细胞凋亡形态的过程中认识到凋 The authors noted in previous studies that there are bright cells (a few) and dark cells (a little) in the human placental cells (Langhans’ cells) [1]; the metaplastic cells of the gestational vesicles in the hydatidiform mole also have bright cells And dark cells (a little) the difference [2]. In the application of DNA nick end labeling technology and electron microscopy combined with the study of human gestational trophoblast apoptosis morphology in the process of recognition
