Fig. 5. Growth and migration of an axon bundle through microchannels. (A) Overall view of a Type 2 device, with its enlarged images (A', A''). (B, C) Enlarged images showing the presence and migration of neurons derived from neurospheres, with higher magnification (B', C'). Immunocyto-chemical staining showing the accumulation and migration of a single axon or a bundle of axons through microchannels (C'', D). Type III β-tubulin (Tuj1)-positive neurons are shown in red.
