IMP compatibility for study of topography–drug combinations on cell expansion. A. Three inhibitors (latrunculin B, jasplakinolide, and blebbistatin) were tested for a drug/geometry combination effects on cell behavior. There is a drug/geometry interaction with 200 nm grids and blebbistatin; B. IL-2 secreted in supernatant after 2–3 days of culture on grid geometries with and without Blebbistatin. Two-way repeated measure ANOVA analysis shows significant enhancement in IL-2 secretion with Blebb and 200 nm trench geometry combination. (*, p < 0.02; **, p < 0.3; ***, p < 0.0002).
