人乳腺上皮细胞 (HMEC)在通常情况下可分裂至PD(群体倍增次数 ) 5 5~ 6 0 ,WangJ等(2 0 0 0 )将含有人TERT(端粒酶催化亚单位的cDNA)的逆转录病毒导入PD40的HMEC ,使其可分裂代数延长到PD2 5 0。他们在延至PD1 5 0时用Cre重组酶 (recom?
Human mammary epithelial cells (HMEC) can normally divide to PD (population doubling times) 55-600, and WangJ et al. (2000) will reverse human TERT (cDNA of telomerase catalytic subunit) The virus was introduced into the PD40 HMEC to make it splittable prolonged to PD250. They used Cre recombinase (recom?
