Both the colchicine-resistant Sc9(ColO) and vincristine-resis-tant Sc9(VCR5) cells displayed an accelerated HMBA-induced commitment to terminal cell differentiation, whereas the adriamycin-resistant SC9 (A 120) 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.展开更多
