Abstract

Biochem Biophys Res Commun. 1995 Nov 2;216(1):49-53. Human satellite cell proliferation in vitro is regulated by autocrine secretion of IL-6 stimulated by a soluble factor(s) released by activated monocytes. Cantini M, Massimino ML, Rapizzi E, Rossini K, Catani C, Dalla Libera L, Carraro U. Source Department of Biomedical Sciences, University of Padova, Italy. Abstract We previously showed that macrophages, besides their scavenger role, selectively induce rat myoblast proliferation in vitro by releasing soluble factors. In this paper we demonstrate a relationship between human-activated monocytes and increased human myoblast proliferation due to IL-6 autocrine secretion by satellite cells. Indeed in the supernatants of muscle cultures treated with activated monocyte-conditioned medium we show by means of an ELISA quantitation a higher autocrine secretion of IL-6 associated with increased myoblast proliferation. This suggests that a growth factor(s) secreted by activated monocytes stimulates IL-6 production by myoblasts and then regulates proliferation of satellite cells.
