细胞凋亡现象普遍地存在于胚胎发育、细胞分化、组织更新等生进过程中，也见于肿瘤、免疫缺陷、器官萎缩等病理过程中，因而引起了各学科越来越广泛地关注。细胞凋亡在胚胎发育中起着极其重要的作用，本文拟对胚胎发育过程中的细胞凋亡现象、机制、作用及其与畸形的关系作一简要概述。 Apoptosis generally exists in embryonic development, cell differentiation, tissue regeneration and other birth processes, but also found in the pathology of tumors, immune defects, organ atrophy and so on, which has attracted more and more attention of all disciplines. Apoptosis plays an extremely important role in embryonic development. In this paper, the phenomenon of apoptosis in embryonic development, its mechanism, its function and its relationship with deformity are briefly summarized.
