Fig. 3. Fluorescent microscope images of rat cardiomyoblasts (H9c2) cells on PCL, PCL–PVDF and PCL–PANI–PVDF on days 1, 2, 3 and 7. The nuclei were stained with DAPI (blue) and F-actin filaments were stained with Alexa Fluor® 488 Phalloidin (green). Images captured at 20× magnification. The cells are aligned on PCL–PANI–PVDF and have a defined orientation as compared to PCL and PCL–PVDF scaffolds. The cells also infiltrated the scaffolds in the PCL–PANI–PVDF as indicated by the blurred regions present at different depths of the scaffold.
