Abstract：
:Primary brain tumors lack the metastatic behavior that is in part believed to be promoted by the extracellular matrix (ECM) components of the basement membrane. This study was intended to examine the influence of the ECM components present in the basement membrane that may act as natural barriers to tumor cell invasion. We examined the effect of type I and type IV collagens, fibronectin, laminin, and hyaluronic acid on the migration and invasion of four established glioblastoma cell lines, SNB19, U251, UWR1, and UWR2. Lower concentrations of all the ECM components induced the migration and invasion of all the cell lines. However, in the case of SNB19, laminin inhibited both migration and invasion in a concentration-dependent manner. We have also examined the influence of individual ECM components on the migration of cells from a spheroid to a monolayer on ECM component-coated coverslips. Consistent with the invasion studies using the modified Boyden chamber assays, lower concentrations of ECM components induced the migration of cells from spheroids to monolayer. Again, laminin inhibited the migration of cells from SNB19 spheroids. These results indicate that ECM components induce the invasion of glioma cells, apart from components like laminin, which may act as natural inhibitors.
