From: Cell behaviour on a polyaniline nanoprotrusion structure surface
Fluorescence images of the morphology of MC3T3-E1 cells adhering to the surfaces 4 days after seeding. (a and b) Polyaniline nanoprotrusion structure surface (PNS). (c and d) Tissue culture plate (TCP). (a) and (c) show DAPI and phalloidin staining. (b) and (d) show SEM images of the morphology of cell adhesion to the surfaces. The inset in (b) is a higher-magnification image of filopodia on PNS. The bottom graph shows the area of osteoblast cell adhesion. The scale bars in (a) and (c) are 50 μm, those in (b) and (d) are 10 μm, and the scale bar in the inset image in (b) is 1 μm.
