Abstract

The hepatic wound repair process involves cell types including healthy and injured hepatocytes, Kupffer and inflammatory cells, sinusoidal endothelial cells (SECs), and hepatic stellate cells (HSCs). Normally, in their quiescent state, HSCs are a reservoir for vitamin A, but in response to hepatic injury, they become activated myofibroblasts that play a key role in the hepatic fibrotic response. Activated HSCs express extracellular matrix (ECM) proteins, elicit anti-apoptotic responses, and proliferate, migrate, and invade hepatic tissues to protect hepatic lobules from damage. Extended liver injury can lead to fibrosis and cirrhosis, the deposition of ECM that is driven by HSCs. Here we describe in vitro assays that quantify activated HSC responses in the presence of inhibitors targeting hepatic fibrosis.
