The spheroid-forming ability, colony formation and chemotherapy susceptibility in CD44+ and CD44− cells isolated from MKN45 cells. (A) CD44+ MKN45 cells formed a greater number of spheroids compared with CD44− MKN45 cells. (B) CD44+ MKN45 cells were more chemoresistant compared with CD44− cells. Data are presented as the mean ± SD; n=5. *P<0.05.
