Abstract: |
Several drug-resistant variants have been developed by growing the parental MEL cells in presence of colchicine, adriamycin and vincristine respectively with stepwise increasing concentration. Both the colchicine-resistant Sc9(Co10) and vincristine-resistant Sc9(VCR5) cells displayed an accelerated HMBA-induced commitment to terminal cell differentiation, whereas the adriamycin-resistant SC9 (A120) showed no acceleration but rather a substantial delay in HMBA-induced differentiation. The studies provide more clues as well as experimental models for further study on the mechanism of induced differentiation of MEL cells. © 1989 Chinese Journal Of Cancer Research. |
