目的 :本文提出胎盘滋养细胞结是 Keer描写的凋亡小体以外的另一种凋亡形态。方法 :用电镜系统地观察 :人胎盘滋养细胞生长、发育和衰老 ,并进一步用 DNA缺口标记做了对比观察。结果 :合体细胞结终末超微结构符合细胞凋亡形态特征。讨论 :胎盘滋养细胞凋亡从分子水平开始至超微结构及细胞形态变化是一个发展过程。
OBJECTIVE: This paper proposes that the placental trophoblastic junction is another apoptotic morphology other than apoptotic bodies described by Keer. Methods: Observing electron microscopy: human placental trophoblast cell growth, development and aging, and further DNA gap markers were compared. Results: The terminal ultrastructure of syncytial cell junction was consistent with the morphological features of apoptotic cells. Discussion: Placental trophoblast apoptosis from the molecular level to the ultrastructure and cell morphology changes is a development process.
