GAG and total collagen content normalized by sample wet weight (A, B) and calcium content normalized by sample dry weight (C) of MSC-laden HA hydrogel constructs after 14 days of in vitro culture followed by 28 days of subcutaneous implantation in nude mice (42 days in total). Images of the harvested MSC-laden HA hydrogel implants (scale bar = 2 mm), immunohistochemical staining for chondroitin sulfate (CS) and type II collagen (Col 2) (scale bar = 50 μm) and Von Kossa staining of MSC-laden HA hydrogel constructs on day 42 (scale bar = 500 μm) (D). *p < 0.05 vs. 5% 15 min group at the same culture time; (n = 4).
