The author studied the changes in the mitotic cycle of ascites hepatoma 22A cells under artificially created unfavourable conditions. It was shown that as a result 3 tumors of 6-day development united. In the early stage of such a union there was a blockade in passage from G1 in S period and from G2 in mitosis. The cells which were in S period at the moment of union accumulated in G2 period and passed to the irreversible resting state. In the course of the union the cells in G1 period completely preserved the ability to complete the mitotic cycle.
作者研究了在人为创造的不利条件下腹水型肝癌22A细胞有丝分裂周期的变化。结果表明，6天发育的3个肿瘤合并在一起。在这种合并的早期，从G1期进入S期以及从G2期进入有丝分裂期均出现阻断。合并时处于S期的细胞积聚在G2期并进入不可逆的静止状态。在合并过程中，处于G1期的细胞完全保留了完成有丝分裂周期的能力。
