DNM2 and neoplasm: Thus the Authors explored the changes occurring in the conditioned medium of MSCs co‐cultured with U87: regardless from TGFβ expression, 126 proteins with 10 new expressed proteins were detected, some of which exclusively found after cell‐to‐cell contact, such as profilin2 (PFN2), which regulates actin polymerization, cortactin, a cytoskeletal protein overexpressed in invasive tumor cells, and ezrin, an invasion‐associated protein, indicating that UC‐MSC may exert pro‐tumorigenic effects when in close contact with tumor cells.126
