HGF is a protein produced by fibroblasts and acts by binding the receptor tyrosine kinase c-Met expressed on nearby epithelial cells, endothelial cells, and fibroblasts (Bogatkevich et al., 2007a,b; Crestani et al., 2012). Some autocrine fibroblast factors counteract fibrosis, such as the hepatocyte growth factor (HGF). 159, 13131321. WebIn the liver, the dominant source of myofibroblasts are HSCs, which, in response to liver injury, transdifferentiate from quiescent, lipid-laden cells into fibrogenic and contractile myofibroblasts. Fibroblasts also play a role in blood clotting, such as in the production of urokinase plasminogen activators (PAs) and their inhibitors (PAIs). (2012). This strategy found no appreciable contribution of pericytes to the expansion of myofibroblasts and the resulting fibrosis even though the pericyte population itself did expand significantly (Rock et al., 2011).

Toll-like receptor 4 signaling augments transforming growth factor-beta responses: a novel mechanism for maintaining and amplifying fibrosis in scleroderma. Myofibroblasts can differentiate from a variety of precursor cell types. In addition, some fibroblasts, referred to as myofibroblasts, have contractile properties and play a critical part in wound healing. Akt1 mediates alpha-smooth muscle actin expression and myofibroblast differentiation via myocardin and serum response factor.

Further, SSc patients with pulmonary fibrosis have significantly higher levels of circulating TN-C compared with SSc patients without pulmonary fibrosis (Brissett et al., 2012). GFP-expressing fibroblasts derived from the multipotent, transgenic bone marrow transplanted into chimeric normal mice appear to be a unique population of cells that do not express SMA and fail to differentiate into myofibroblasts when extracted and stimulated ex vivo in culture (Hashimoto et al., 2004; Kisseleva et al., 2006; Barisic-Dujmovic et al., 2010; Rock et al., 2011).

Histone deacetylase 7, a potential target for the antifibrotic treatment of systemic sclerosis. Up-regulation of cysteinyl leukotriene 1 receptor by IL-13 enables human lung fibroblasts to respond to leukotriene C4 and produce eotaxin. Observations such as the induction of SMA expression in myofibroblasts and the reduction in SMA expression in VSMCs during vascular injury (Yoshida and Owens, 2005) suggest the reduction of a contractile phenotype in VSMCs could also promote another source of myofibroblasts differentiation.
