The anti-tumor effects of Human Wharton’s jelly mesenchymal stem cells derived secretome on MCF-7 and 4T1 tumor cells were determined by MTT assay. Different concentrations of secretome were considered. Statistical differences were calculated between untreated controls and cells treated with hWJMSC-secretome (all experiments were performed triplicated (n=3)). PC refers to positive control (10 mg of cisplatin). (* P<0.05, ** P<0.01, *** P<0.001, and **** P<0.0001)
