The cellular response of RK-13 cells towards in-house synthesised AAO membranes, a commercially available membrane and glass controls were investigated by examining cell adhesion, morphology and proliferation. The in-house membranes were anodized using a two-step procedure to produce a highly ordered hexagonal pore and channel structure.
Results:
Cell proliferation over a 48 h period indicated that the AAO membranes were more than comparable with the glass control substrates. Subsequent microscopy observations revealed evidence of focal adhesion sites and cellular extensions interacting with the underlining porous membrane surface structure.
