Morphology of scaffolds and cultured NSCs on plain scaffold and graphene oxide (GO) coated nanomaterial-nanofiber hybrid scaffold. Field emission scanning electron microscopy (FE-SEM) images of PCL nanofibers (a) and PCL nanofibers coated with 1.0 mg/mL GO solution (b). Scale bars 2 µm. FE-SEM images of oligodendrocytes derived from neural stem cells (NSCs) after 6-days culture on PCL nanofibers (c) and nanomaterial-nanofibers hybrid scaffold (d). Cells are pseudo-colored blue for contrast. Process extension of NSC-derived oligodendrocytes is clearly exhibited when cultured on the nanomaterial-nanofiber hybrid scaffold (d) over PCL nanofiber only control (c). Scale bars 10 µm [70]
