FIG. 2.

Representative fluorescent images of human adipose stromal cells (hASC) cultured for 3 days on random (a, c) and aligned (b, d) nanofiber meshes. Cells were stained with phalloidin-tetramethyl rhodamine isothiocyanate (TRITC) (red) for filament-actin (a, c) or stained with Cy3-conjugated anti-α-tubulin (green). Cell nuclei were stained blue with 4′,6-diamidino-2-phenylindole (DAPI). Double-head arrow indicates the fiber orientation. Scale bar: 50 μm. Color images available online at www.liebertonline.com/tea
