Abstract

Hepatic stellate cells (HSCs), alternatively known as liver pericytes, can differentiate into myofibroblasts and secrete extra-cellular matrix components, thereby promoting wound healing and fibrosis. Studying HSCs can provide insights into the pathological mechanisms governing these processes. HSC isolation methods typically comprise of enzymatic digestion followed by density gradient centrifugation and / or Fluorescent Activated Cell Sorting (FACS) mediated sorting. In this protocol, we describe a step-wise method for HSC isolation that utilizes Pronase and Collagenase for enzymatic tissue dissociation, followed by an Optiprep based density gradient centrifugation. The isolation can be performed using common media and buffers, and without the use of any special equipment for liver perfusion and HSC isolation. The technique yields ex vivo HSCs, suitable for use in assays.
