Oncostatin M promotes mesenchymal stem cell-stimulated tumor growth through a paracrine mechanism involving periostin and TGFBI

- Oncostatin M stimulates tumor growth of prostate cancer in vivo.
- Oncostatin M promotes secretion of periostin and βig-h3 in mesenchymal stem cells.
- Periostin and βig-h3 act as adhesion molecules for prostate cancer cells.
