Figure 5: (A - B) Rat DRG neurons grown (for 7 days) on carbon nanotube (CNT) thread (black), immunostained for neuron-specific tubulin (NST). Arrows A point to neurites A) away from the ganglion on the thread and B) extending out of the ganglion (asterisk). C) Mouse CNS neurosphere cells (grown for 5 days in differentiation medium on laminin-coated thread, see (Hopkins et al., 2010) for culture details) differentiated into neurons (green, NST immunostaining) and astrocytes (red, GFAP immunostaining), with blue stained nuclei (DAPI stain) [42].
