Oncostatin M (OSM) is a member of a cytokine subfamily that includes IL-6, IL-11, LIF, CNTF, and Cardiotrophin-1. These cytokines have overlapping biological functions and shared receptor components. Mouse OSM was cloned and identified as an immediate early gene induced in various myeloid and lymphoid cell lines by a subset of cytokines including IL-2, IL-3, GM-CSF, and Erythropoietin. The mouse OSM cDNA encodes a 263 amino acid residue precursor protein that shows 48% identity with human OSM. Similar to human OSM, the C-terminal region of mouse OSM contains a highly charged region. Deletion of this C-terminal region appears to be essential for the formation of biologically active mouse OSM. The biological activity of human OSM has been shown to be mediated either by the LIF/OSM receptor complex composed of gp130 and LIF R alpha or by a human OSM specific receptor composed of gp130 and OSM R alpha. It remains to be determined if the biological activities of mouse OSM can also be mediated by both receptor complexes in mouse cells.

Cell Proliferation Induced by Oncostatin M/OSM and Neutralization by Mouse Oncostatin M/OSM Antibody
Recombinant Mouse Oncostatin M/OSM (Catalog # 495-MO) stimulates proliferation in the NIH-3T3 mouse embryonic fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse Oncostatin M/OSM (1 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse Oncostatin M/OSM Monoclonal Antibody (Catalog # MAB4951). The ND50 is typically 0.2-1.2 µg/mL.
Detection of Oncostatin M (OSM) by Immunocytochemistry/ Immunofluorescence
OSM increases the migration and proliferation o PDVC57 cells(A)In vitro wounds were made in cultures of mitomycin-treated PDVC57 cells and the cells cultured for a further 48 h, with or without OSM, (10 ng/mL). Cell migration into the wounded area was assessed as described in Materials & Methods. Scale bar: 100 μm. Data are presented as the mean ± SEM of the migration area (mm2) from three independent experiments. Mann-Whitney test, *p < 0.05. (B) PDVC57 cells were cultured, with or without OSM (10 ng/mL), for 48,h. Cells were fixed and stained with an anti-Ki67 antibody (green) and the cell nuclei stained with DAPI (blue). Scale bar: 100 μm. Data are represented as the mean ± SEM of the percentage of Ki67+ cells from three independent experiments. Mann-Whitney test, *p < 0.05, **p < 0.01.

Detection of Oncostatin M (OSM) by Western Blot
PDVC57 cells express functional OSMR type II involved in ERK1/2 and STAT3 signaling and modulation of gene expression(A) Relative mRNA expression of normal murine epidermal keratinocytes (NMEK) and PDVC57 cells cultured under normal conditions for 6 h was measured by real-time qPCR. Data are presented as the mean ± SEM of relative mRNA expression (A.U.). Two-way ANOVA test with Bonferroni post-tests, *p < 0.05, **p < 0.01. (B) PDVC57 cells were cultured with or without OSM (10 ng/mL) for 5 min, 15 min, 30 min, 1 h, or 6 h. Protein levels of P-STAT3, total STAT3, P-ERK 1/2 and total ERK were measured by western blotting. Data are presented as the mean ± SEM of phosphorylated to-total protein ratio for STAT3 or ERK from three independent experiments. Kruskall-Wallis test with Dunn's Multiple Comparison Test, *p < 0.05, **p < 0.01, ***p < 0.001. (C) Scatter-plot graphs representing the relative mRNA expression of PDVC57 cells stimulated, or not, with OSM (10 ng/mL) for 6 or 24 h. The X axis indicates the relative expression in the control and the Y axis the relative expression of OSM stimulated PDVC57 cells. The red dots reflect up-regulated genes and the green dots, down-regulated genes. Total RNA was isolated and labelled according to the Affymetrix protocol. Transcriptional profiles were obtained using Affymetrix GeneChip™ Mouse Gene 2.1 ST Array Plate.
