Patterns of hPDLSCs alignment on the various MEW PCL scaffolds. (A) Representative CLSM images show a variable pattern of cells' bridging, following the fibers' arrangements at day 3 and 7. DAPI (blue) and phalloidin (red) fluorescent staining (scale bar = 50 μm). (B) Histograms of PDLSCs nucleus angulation on scaffolds with aligned and randomly oriented fiber configurations as well as crosshatch 0/90° arrangement and 250 μm and 500 μm strand spacings corresponding to confocal images.
