Abstract:
Mesenchymal stem cells from human adipose tissue (hASCs) are proposed as suitable tools for soft tissue engineering and reconstruction. Although it is known that hASCs have the ability to home to sites of inflammation and tumor niche, the role of inflammatory cytokines in the hASCs-affected tumor development is not understood. We found that interferon-γ (IFN-γ) and/or tumor necrosis factor-α (TNF-α) prime hASCs to produce soluble factors which enhance MCF-7 cell line malignancy in vitro. IFN-γ and/or TNF-α-primed hASCs produced conditioned media (CM) which induced epithelial to mesenchymal transition (EMT) of MCF-7 cells by reducing E-Cadherin and increasing Vimentin expression. Induced EMT was accompanied by increased invasion, migration, and urokinase type-plasminogen activator (uPA) expression in MCF-7 cells. These effects were mediated by increased expression of transforming growth factor-β1(TGF-β1) in cytokines-primed hASCs, since inhibition of type I TGF-β1 receptor on MCF-7 cells and neutralization of TGF-β1 disabled the CM from primed hASCs to increase EMT, cell migration, and uPA expression in MCF-7 cells. Obtained data suggested that IFN-γ and/or TNF-α primed hASCs might enhance the malignancy of MCF-7 cell line by inducing EMT, cell motility and uPA expression in these cells via TGF-β1-Smad3 signalization, with potentially important implications in breast cancer progression. © 2016 International Union of Biochemistry and Molecular Biology.
