Thus, our results revealed a close correlation between the disruption of cell-matrix interactions and the subsequent activation of the PTEN phosphatase.
Previously, studies of phenotypes in this laboratory have shown that SPARC-null mice develop osteopenia around 2.5 months of age [ 19 ] in bones where SPARC is normally the most abundant non-collagenous glycoprotein [ 3 ] . The second phenotype thus far uncovered is in the lens where SPARC is normally produced by lens epithelial cells [ 20 21 ] and is a component of the lens capsule [ 20 22 ] . SPARC-null mice show progressive cataract formation beginning approximately 1.5 months after birth [ 14 21 ] . Electron microscopy of the SPARC-null lens revealed abnormality at the lens cell-ECM (capsule) interface with an intrusion of cellular processes into the basement membrane of the lens capsule, whereas wild-type lens exhibited a precise border at the cell-matrix interface [ 23 ] . In the present study, we show for the first time that SPARC plays a role in wound repair in vivo and in vitro.
TSP-1 is a homotrimeric multidomain glycoprotein synthesized and secreted by numerous cell types, including platelets, vascular smooth muscle cells and keratinocytes [ 4 ] . Due to its interaction with a wide variety of proteins, TSP-1 has been implicated in a number of biological processes including coagulation, cell adhesion, the modulation of cell-cell and cell-matrix interactions, control of tumor growth and metastasis, and angiogenesis [ 10 ] . Inhibition of tumor cell proliferation has been achieved in vivo by systemic treatment with TSP-1 peptide mimetics [ 11 ] , but a correlation between primary tumor TSP-1 expression and poor prognosis has not been clearly established [ 12 ] . While there are reports that these molecules can originate from tumor cells [ 13 ] , the majority of reports have suggested that the major source of both TSP-1 and OPN is tumor-associated stroma [ 14 ] or infiltrating macrophages and lymphocytes [ 15 ] .
Because essentially all of these previous studies have analyzed PTEN function by introducing the cloned version of the gene back into PTEN-deficient cells, essentially nothing is known about the regulation of the endogenous PTEN gene in response to alterations of cell-matrix interactions.
In view of PTEN's potent growth-inhibitory capacity, we conclude from our study that the increased expression and activity of endogenous PTEN in response to the disruption of cell-matrix interactions contributes to the maintenance of the anchorage-dependent phenotype of normal cells.
