Effect of BaTiO₃ content on the in vitro properties of the piezoelectric scaffolds. (a) OD readings of the MC3T3 cells cultured on the PCL and various piezoelectric PCL-BT scaffolds; 1 MHz US were used per the routine for all the proliferation test. * means statistically significant (p < 0.05) with respect to PCL specimens. # means statistically significant (p < 0.05) with respect to the specimens in the “3 days” group. SEM images of the adhered MC3T3 cells on various scaffolds (b) after day 1 and (c) after day 7 of culture.
