Abstract
Breast cancer is the most commonly diagnosed cancer among women worldwide. In recent years, there has been growing interest among researchers in exploring alternative therapeutic methods, including stem cell therapy. Therefore, this study aimed to investigate the effects of adipose-derived mesenchymal stem cell-conditioned media (AD-MSCs-CM) on apoptosis induction and migration inhibition of breast cancer cells (MDA-MB-231) in vitro. Here, malignant breast cancer cells (MDA-MB-231) and adipose mesenchymal stem cells (AD-MSC) were cultured separately in DMEM F12/FBS15% culture media in standard conditions. Subsequently, the conditioned media derived from AD-MSCs was exposed to the MDA-MB-231 cells. After 24 and 48 hours of exposure, the expression levels of CASP3, KRAS, and MMP9, were assessed using a qRT-PCR assay. Additionally, the proliferation and migration abilities of the cancer cells were evaluated using MTT and wound healing assays, respectively. Also, the protein expression of Caspase-3, K-RAS, and MMP-9 was examined using the western blot assay. Notably, the expression level of MMP9 and KRAS genes significantly decreased following AD-MSCs-CM treatment in MDA-MB-231 cells. Moreover, the expression level of CASP3 gene remarkably increased in the treated groups. Besides, the proliferation of MDA-MB-231 cells treated with AD-MSCs-CM was strongly reduced by MTT and wound healing assays. Furthermore, the AD-MSCs-CM demonstrated an increase in the activation of Caspase-3 and a decrease in the protein expressions of K-RAS and MMP-9. The findings of this study suggest that the AD-MSCs-CM have the potential to influence apoptosis, proliferation, and migration of breast cancer cells. Thus, it could be considered a promising therapeutic strategy for suppressing breast cancer. However, further testing and research are required to validate these findings and explore the full potential of this approach.
