【摘要】 人参皂甙在体外短期培养中,能诱导ARS细胞在细胞表型、非特异性酯酶活性和吞噬功能方面,出现巨噬细胞样分化,并能抑制瘤细胞的DNA合成和核分裂。人参皂甙组瘤细胞、核、核仁及核浆比值明显减小;表面微绒毛减少,出现皱褶;线粒体小,数量增多,大小一致,分布规则;非特异性酯酶活性增高;吞噬功能增强。特别是诱导增多的小细胞,上述变化更明显,是一种分化程度高的巨噬细胞样细胞。更多还原

【Abstract】 Our study demonstrated that ARS cells can be induced to differentiate into macrophage-like cells with changes in phenotype, nonspecific esterase activity and phagocytic function by adding ginsenosides in short-term cultures. Synthesis of DNA, mitosis and the growth of the culture cells transplanted in mouse are also inhibited in this condition. The size of cells, nuclei and nucleoli, as well as nuclear-cytoplasmic ratio of ginsenosides treated cells are diminished significantly. Microvilli of these cells are reduced in number with formation of. ruffles on the cell surface. Mitochondria are increased, their size and distribution become regular. The fact that numerous small cells, induced by ginsenosides exhibit the most conspicuous alteration mentioned above along with marked phagocytic activity indicates that they are highly differentiated macrophage-like cells. Whether the inhibition of cell growth and induction of differentiation by ginsenosides is caused through its action on the molecules regulating the gene expression of cell growth and differentiation needs further study.更多还原
