ABSTRACT:
The present invention relates to precursor cells to hepatic stellate cells, compositions comprising same and methods of isolating same. The surface antigenic profile of the precursors is MHC class Ia negative, ICAM-1+, VCAM-1+, β3-integrin+. In addition to expression of these surface markers, the cells also express the intracellular markers desmin, vimentin, smooth muscle α-actin, nestin, hepatocyte growth factor, stromal derived factor-1α and H1x homeobox transcriptional factor.
