Here, we analyzed the early impact of BMC infusion and identified the subsets of BMCs showing antifibrotic effects in mice with carbon tetrachloride\u2013induced liver fibrosis. An interaction between BMCs and activated hepatic stellate cells (HSCs) was investigated using an<\/jats:bold>\n \n in vitro\n <\/jats:bold>\n coculturing system. Within 24 hours, infused BMCs were in close contact with activated HSCs, which was associated with reduced liver fibrosis, enhanced hepatic expression of interleukin (IL)-10, and expanded regulatory T cells but decreased macrophage infiltration in the liver at 24 hours after BMC infusion. In contrast, IL-10\u2013deficient (IL-10\u2212\/\u2212) BMCs failed to reproduce these effects in fibrotic livers. Intriguingly, in isolated cells, CD11b+Gr1highF4\/80\u2212 and CD11b+Gr1+F4\/80+ BMCs expressed more IL-10 after coculturing with activated HSCs, leading to suppressed expression of collagen and \u03b1-smooth muscle actin in HSCs. Moreover, these effects were either enhanced or abrogated, respectively, when BMCs were cocultured with IL-6\u2212\/\u2212 and retinaldehyde dehydrogenase 1\u2212\/\u2212 HSCs. Similar to murine data, human BMCs expressed more IL-10 after coculturing with human HSC lines (LX-2 or hTERT), and serum IL-10 levels were significantly elevated in patients with liver cirrhosis after autologous BMC infusion.<\/jats:bold>\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion :<\/jats:title>\n \n Activated HSCs increase IL-10 expression in BMCs (CD11b+Gr1highF4\/80\u2212 and CD11b+Gr1+F4\/80+ cells), which in turn ameliorates liver fibrosis. Our findings could enhance the design of BMC therapy for liver fibrosis.<\/jats:bold>\n <\/jats:p>\n
