Fig. 8From: Human nasal septal chondrocytes (NSCs) preconditioned on NSC-derived matrix improve their chondrogenic potentialChondrocyte differentiation of the preconditioned NSCs upon subcutaneous transplantation in vivo. Analysis of subcutaneously transplanted mesh scaffolds at 3 weeks: a Representative immunofluorescence images exhibit the positive signals of COL II (green) in the mesh scaffolds, along with DAPI (blue) staining. b The NSCs-derived, newly synthesized GAG is detected via Safranin O/fast green staining of mesh scaffolds. The boxed region is enlarged in a high resolution, where M is the mesh scaffold, PM is a pericellular matrix (GAG), and C is chondrocyte (NSC)Back to article page
