Abstract
Complex interactions between cells and the extracellular matrix are requisite during development, wound repair, and neoplasia. Proteins that regulate cell-cell and cell-matrix contacts are likely to influence both normal responses (e.g. wound healing) and abnormal processes (e.g. malignant transformation). The glycoprotein SPARC (secreted protein, acidic and rich in cysteine), also termed osteonectin, BM-40, and 43 K protein, has been classified, along with tenascin and thrombospondin, as an “anti-adhesinan ” (for review see Sage and Bornstein 1991). For many cell types, this function promotes cell rounding, a decrease in focal adhesions, and diminished cell-cell and cell-surface contacts. The at¬tendant consequences for tissue remodeling and cellular migration implicate SPARC as a regulatory protein in both wound healing and cancer. The purpose of this chapter is to review the properties of this protein and the functional implications for SPARC in neoplasia and tissue repair.
