Fig. 2From: Hydrophilic nanofibers with aligned topography modulate macrophage-mediated host responses via the NLRP3 inflammasomeFabrication of aligned and disordered electrospun nanofibers. (A, B) SEM images and the orientation, energy, coherency and HSB color-coded maps of aligned and random PCL nanofibers. (C, D, E) Determination of the orientations of aligned and random fibers as visualized by Fourier and radar charts. (F) SEM images showing macrophages different morphologies attached to TCP substrates (left panel), random nanofibers (middle panel) and aligned nanofibers (right panel)Back to article page
