细胞凋亡（ａｐｏｐｔｏｓｉｓ）在生物体发育形成及功能维持中起着重要作用，由于某些原因，细胞凋亡与疾病特别是肿瘤有密切关系。本文用原位末端标记法（ＴＵＮＥＬ）特异地原位显示人大肠腺癌细胞凋亡的形态特点，探讨其生物学意义。１材料与方法所有研究材料取自本科... Apoptosis plays an important role in the development and function maintenance of organisms. For some reasons, apoptosis is closely related to diseases, especially tumors. In this paper, the morphological characteristics of apoptosis in human colorectal adenocarcinoma cells were specifically demonstrated in situ using TUNEL, and its biological significance was explored. 1 Materials and Methods All research materials were taken from undergraduate students...
