(b) Representative images showing superimposing between DAPI (blue), collagen II (green), and aggrecan (red) signals of AFSC samples 1–4 after three weeks of culture in chondrogenic medium. (c) Representative images showing superimposing between DAPI (blue), GFAP (green), and βtubulin III (red) signals of AFSC samples 1 and 4 after three weeks of culture in neurogenic medium.
