Endothelial cell adhesion increased on fine grain NiTi substrates with greater submicron to nanometer surface features after 5 hours, *p < 0.01 compared to all other substrates. The difference in endothelial cell adhesion between coarse grain NiTi, c.p. Ti, and the control was not significant. Data = mean +/− S.E.; N = 3. Control = tissue culture polystyrene.
