Conditioned media from human adipose tissue-derived mesenchymal stem cells: potential effect on peripheral blood mononuclear cells in co-culture with HeLa cell line.

The use of mesenchymal stem cells (MSCs) for the treatment of various diseases is being investigated, however, their use in cervical cancer has not been well-studied. Here, we examined the impact of collected MSC-conditioned medium (CM) on 1 to 5 days on apoptosis, proliferation, and cytokine production of peripheral blood mononuclear cells (PBMCs) when co-cultured alongside the HeLa cell line for 24, 48, and 72 h by CFSE assay, flow cytometry, and real-time PCR, respectively. We found that CMs collected on the third day of MSCs culture significantly increased the proliferation of PBMCs and decreased the proliferation of HeLa cells after 48 h.
