BCAR4 expression was significantly increased in CRC cells and ALDH+ cells. a, b qRT-PCR results revealed that expression of BCAR4 in CRC tissues and several CRC cell lines (HCT-116, SW480, HCT-8). c, d qRT-PCR was used to examine the expression of ALDH, CD133, SOX2, NANOG, OCT4, CD44, Lgr5 and BCAR4 in ALDH+ or ALDH− CRC cells. *P < 0.05, **P < 0.01, ***P < 0.001 vs. control
