Enhancement of BM-MSC-CM on the chemoresistance of ovarian cancer cells

(a) Proliferative curves for SKOV3 and COC1 ovarian cancer cells treated with or without BM-MSC-CM under a normal or a cisplatin-containing condition (0.5 mg/L, for 24 h). (b) Colony formation abilities of SKOV3 and COC1 cells treated with or without BM-MSC-CM under a normal or a cisplatin-containing condition (0.5 mg/L). ^* P<0.05, ^** P<0.01, ^*** P<0.001, two-sided Student’s t-test. Data are expressed as mean±standard deviation (SD). CDDP: cis-Dichlorodiammine platinum (II)
