Liver fibrosis is the wound healing process of liver in response to external stimuli. It involves complex multicellular responses and is often induced by chronic liver injury (Friedman, 2008).A common outcome of progressive liver fibrosis is liver cirrhosis, and China accounts for 11% of global liver cirrhosis-related deaths (Asrani …
