In the present study, the effect of X rays on el 4 cell doubling time and cell cycle progression were investigated.
目的研究不同剂量X射线照射对EL4淋巴瘤细胞周期进程及细胞倍增时间的影响。
Results Population doubling time of corneal stromal cells prolonged significantly since passage 7. MTT assay also showed cell viability of passage 7 decreased to 60% of passgage 1 (P< 0. 01 ).
细胞群体倍增时间由第7代起显著延长（P<0.01）；MTT比色法的结果亦显示，第7代细胞的增殖能力开始大幅下降（P<0.01）。
