Stromal derived factor 1 (SDF-1) is a CXC chemokine important in the homing process of stem cells to injured tissue. It has been implicated in healing and tissue repair. Growing evidence suggests that the glycoprotein-130 (gp130) ligand family is involved in repair processes in the heart. The aim of our study was to determine whether gp130 ligands could affect SDF-1 expression in cardiac cells. Human adult cardiac myocytes (HACMs) and fibroblasts (HACFs) were treated with gp130 ligands. Protein and mRNA levels of SDF-1 were determined using ELISA and RT-PCR, respectively. mRNA levels of SDF-1 were determined in human and mouse heart samples by RT-PCR. HACMs and HACFs constitutively express SDF-1, which was significantly up-regulated by the gp130 ligand oncostatin M (OSM). This effect was counteracted by a p38 inhibitor and to a lesser extent by a PI3K inhibitor. mRNA expression of SDF-1 in hearts of mice injected with OSM increased significantly. Levels of OSM and SDF-1 mRNA correlated significantly in human failing hearts. Our data, showing that OSM induces SDF-1 protein secretion in human cardiac cells in vitro and murine hearts in vivo , suggest that OSM via the induction of SDF-1 might play a key role in repair and tissue regeneration.—Hohensinner, P.
