近年来,端粒(telomere)与端粒酶(telomerase)的研究正逐步成为医学界关注的热点。大量的研究证明,人体除了有快速增殖能力的淋巴造血系统细胞、皮肤基底层细胞、增生期子宫内膜细胞等细胞外,其余绝大多数体细胞都不表达端粒酶活性,良性肿瘤细胞也不表达端粒酶活性,而90%以上的
In recent years, telomere and telomerase research are gradually becoming the focus of medical attention. A large number of studies have shown that, in addition to human body rapidly proliferating lymphoid hematopoietic cells, basal cells of the skin, proliferative endometrial cells and other cells, the vast majority of somatic cells do not express telomerase activity, benign tumor cells Does not express telomerase activity, while more than 90%
