Effect of adipose-derived stem cell-conditioned medium on the proliferation and migration of B16 melanoma cells

Adipose-derived stem cells (ASCs) are a population of cells derived from adipose tissuc..ASCs exhibit multilineage development potential and are able to secrete various factors, which influence adjacent cells. Previous studies have reported the effectiveness of ASC-conditioned medium (ASC-CM) in wound healing, anti-mclanogencsis, wrinkle improvement and hair growth. In the present study, the anticancer function of ASC-CM was investigated in vitro and in vivo. An MIT assay revealed that ASC-CM significantly decreased the proliferation of B16 melanoma cells in a time- and dose-dependent manner (P<0.01l). Cell cycle analysis indicated that ASC-CM significantly increased the number of cells in G1 phase while reducing the number of cells in the S and GIM phases (P<0.01l). Furthermore, a wound migration model demonstrated that ASC-CM treatment significantly decreased the migration ability of B16 melanoma cells (P<0.01). In addition, C57131_16 mice were administered with a single intratumoral injection of ASC-CM, daily or every other day, and a significant reduction in the volume of the tumor mass was observed compared with that of the control group (P<0.01). Thus, the.findings of the present study indicated that ASC-CM has an anti-tumorigenic effect on B16 melanoma cells in vitro and in vivo, and may potentially be used to support the treatment of melanoma in the future.
