Abstract

Oncostatin M (OSM) is a multifunctional cytokine that belongs to the interleukin (IL)-6 family. Although there have been a number of studies that focused on the role and mechanism of OSM in various organs and tissues, there are few reports on its effect on wound healing. The purposes of this study are to evaluate the effect of OSM on proliferation and matrix synthesis of dermal fibroblasts. In particular, this study focused on cell proliferation, collagen and glycosaminoglycan (GAG) syntheses (which are the major components of the extracellular matrices). Excess skin that was obtained from patients who underwent skin grafts, was used for this study. From this material, fibroblasts were isolated and cultured. The cultured fibroblasts were treated with one of four concentrations of OSM. The OSM concentrations used were 0, 50, 100, and 200 ng/ml. After the OSM treatment, cell proliferation was determined by the MTT assay, collagen synthesis by the C1CP method, GAG levels by the Blyscan Dye method. Subsequently, the results of each group were compared. OSM treatment increased all the components tested in the study. In particular, cell proliferation, GAG synthesis demonstrated statistically significant increases (p＜0.05 in the Mann-Whitney U-test). The highest increase in all the components was obtained at a 100 ng/ml concentration of OSM. The results from the present study indicate that OSM stimulates proliferation and matrix synthesis of human normal dermal fibroblast and the optimal concentration for wound healing is 100 ng/ml.
