Controlled delivery of rAAV-lacZ (A) or rAAV-FLAG-hsox9 (B) via polypseudorataxane hydrogels. Pellets were cultured in the absence (positive control; free rAAV form) or presence of rAAV-loaded hydrogels systems (Pluronic® F68 (PF68)/ chondroitin sulfate (CS)/alpha-cyclodextrins (α-CD) or PF68/ hyaluronic acid (HA)/α-CD) for 21 days and monitored for chondrogenic differentiation (A,B: Toluidine blue staining: magnification ×4, all representative data) and β-galactosidase activity (A: β-gal immunounoreactivity: magnification ×20, all representative data).
