FIG. 3. — Confocal microscopy of U251 glioma cells detected by nuclear red and cytoplasmic green fluorescence on random (A) and aligned (B) PCL fibers. Random fibers in (A) are shown under phase contrast illumination; aligned fibers in (B) are shown under fluorescent illumination and appear green due to internal reflection of fluorescence. Scale bars: 100 μm. The growth curve of U251 glioma cells cultured on TCPS, aligned nanofibers, and random nanofibers is shown in (C). Color images available online at www.liebertonline.com/ten.
