Background: SPARC

SPARC (secreted protein, acidic and rich in cysteine). SPARC is produced by fibroblasts, capillary endothelial cells, platelets, macrophages, bone, and many tumor cells. It inhibits cell adhesion, spreading and proliferation, promotes collagen matrix formation and osteoblast differentiation, and binds and sequesters PDGF and VEGF. SPARC can be cleaved by metalloproteinases, producing a copper binding angiogenic peptide. SPARC is bound and internalized by Stabilin-1 on alternatively activated macrophages.
