Alcian blue (GAG) stained histological sections of the hMSCs encapsulated in Superficial (B), Middle (C), and Calcified (D) gels and incubated in chondrogenic medium supplemented with zone-specific growth factors. H&E stained sections for the hMSCs encapsulated in Superficial (F), Middle (G), and Calcified (H) gels and incubated in chondrogenic medium supplemented with zone-specific growth factors. Images A and E are for the hMSCs encapsulated in the 80 kPa gel and incubated in basal medium as the control.
