SEM images of hESCs on various substrates. SEM images of (a) cells cultured on PLO exhibiting a flat morphology and two-dimensional axonal connections, (b) cells cultured on silk scaffolds demonstrating three-dimensional structures and cell migration, and (c) cells cultured on silk-CNT scaffolds demonstrating three-dimenstional axonal connections and silk-CNT matrix degradation.
