Abstract Aim: In the current study, CM anticancer function of the MCF7 cells was investigated in vitro.
Material and Methods: Adipose stem cells were extracted from the cesarean women’s abdominal fat with their written informed consent at the Velayat hospital, Damghan. CM was prepared for fourth passage of hASCs that was cultured in serum-free medium for 72h. MCF7 cells were exposed to CM for 24 and 48 hours. Then cell proliferation rate, survival and apoptotic gene expression were determined using MTT, cell counting (hemocytometer) and RT-PCR.
Results: CM-treated MCF7 for 24 and 48h, showed a significant decrement in cell proliferation and viability as compared to the cells cultured in medium containing serum (control). In addition, caspase3 gene expression of CM-induced cells was increased significantly at 24 and 48h as compared to the control group. While, CM-treated cells showed a significant increment of caspase9 gene expression after 48h induction.
Conclusion: It was concluded that CM induced apoptosis by activation of caspases and reduced proliferation rate and survival of MCF7 cancer cells. Therefore, it seems that conditioned medium can be used as a supplement with other anti-cancer therapies.
