对肿瘤细胞表面膜的调控研究是目前肿瘤细胞逆转研究中的一种新的探索,硫杂脯氨酸是继cAMP之后的又一种逆转类药物,对肿瘤细胞表面膜有一定的调控作用。我们通过对膜表面电荷的研究,看到硫杂脯氨酸能使肝癌细胞表面膜电荷含量向正常细胞的状态转化。关于肿瘤细胞和正常细胞表面电荷的比较研究,发现大多数肿瘤细胞比其同 The research on the regulation of tumor cell surface membrane is a new exploration in the current research of tumor cell reversion. Thiaproline is another kind of reverse drug after cAMP, which has a certain regulatory effect on the surface membrane of tumor cells. By studying the surface charge of the membrane, we can see that thiamidine can convert the surface membrane charge of hepatoma cells into normal cells. A comparative study of the surface charge of tumor cells and normal cells found that most tumor cells are more homogeneous than
