Expression of SPARC in normal and fibrotic livers
Edward Frizell, Shu‐Ling Liu, Ann Abraham, Iwata Ozaki, Mahboubeh Eghbali, E. Helene Sage, Mark A. Zern – 1 March 1995 – SPARC (secreted protein, acidic and rich in cysteine)—also known as osteonectin, BM‐40, and 43K glycoprotein—is secreted by endothelial cells and fibroblasts in response to culture shock. SPARC has been found in association with tissues undergoing cell proliferation, migration, and extracellular matrix remodeling. We demonstrate that normal livers from humans, rats, and mice express substantial levels of SPARC messenger RNA (mRNA).
