SU11652 effectively inhibits the growth of MV-4-11 cells. A. MV-4-11, HL-60, Karpas 299, and Jurkat cells were cultured in the presence of various concentrations of SU11652 for 48 hours. Cell viability was assessed by MTT assays. Error bars denote standard deviation (n = 3). B. Wright-Giemsa staining of MV-4-11 and HL-60 cells treated with 0 or 100 nM SU11652 for 48 h. Black arrows point to mitotic cells.
