Abstract: The invention discloses a quasi in-vivo testing method using a uniquely designed multichambered bioblock apparatus. Cells are placed inside a top chamber fitted with a pore size membrane that allows certain cells to migrate through the pores into a bottom chamber holding a substrate. The portion of cells migrating from the top chamber and interacting with the substrate surface in a real time physiological quasi in vivo environment can be used to determine both the migratory response of specific cell types to selected attractive surfaces and the effect of the migratory cells on the surface over selected times of exposure.
