(A) Concentration of sulfated glycosaminoglycan (sGAG) as a percent of the construct wet weight (%ww) in MSC-laden methacrylated HA (MeHA) and agarose (Ag) hydrogels at seeding densities of 20 million MSCs/mL (20M) and 60 million (60M) MSCs/mL after 1 (white), 28 (grey), and 56 (dark grey) days of in vitro culture in a chemically defined chondrogenic medium with TGF-β3 (10 ng/mL). (n=4 constructs per group; bars indicate p<0.05) (B) Alcian blue staining of proteoglycans after 56 days in MSC-laden HA and Ag constructs at 20M and 60M seeding densities.
