本文用透射与扫描电镜方法研究了抑癌因子对Ehrlich腹水癌细胞的作用。发现,在抑癌因子作用下,肿瘤细胞内部结构破坏,表面形态趋于简化。在抑癌因子作用早期(4—8小时),肿瘤细胞聚集能力增加,这种变化可能具有肿瘤专一性;在抑癌因子作用18小时时,肿瘤细胞聚集能力下降,这可能与此时细胞大部分死亡有关。 In this paper, the effect of tumor suppressor factors on Ehrlich ascites cancer cells was studied by transmission and scanning electron microscopy. It was found that under the action of tumor suppressing factors, the internal structure of tumor cells is destroyed, and the surface morphology tends to be simplified. In the early stage (4-8 hours) of tumor suppressor factors, the ability of tumor cells to accumulate increases, and this change may have tumor specificity; when tumor suppressor factors act 18 hours, the ability of tumor cells to aggregate decreases, which may be at this time Most deaths are related.
