骨髓巨核细胞作为血小板生成来源从上一世纪以来被人们探究。(1～5)目前电子显微镜观察尤其走差电子显微镜(即扫描电子显微镜)的应用,非常形象地拍照下了血小板形成和排出过程(10)。关于巨核细胞的命运方面虽有各种报导,但我们在长期观察中看到一种现象,在本文里作一简要叙述。材料及方法 As a source of platelet production, bone marrow megakaryocytes have been explored since the last century. (1 ~ 5) The current electron microscope observation, especially the use of electron microscopy (ie scanning electron microscopy), very vividly photographed platelet formation and discharge process (10). Although there are various reports on the fate of megakaryocytes, we see a phenomenon in long-term observation and make a brief introduction in this article. Materials and methods
