The chondrogenic bioactivity on ADSCs of curcumin-loaded PEG-GelMA microgel (PGMs). (A) Schematic of ADSCs culture on the curcumin-loaded PEG-GelMA microgel (PGMs) and further tri-lineage differentiation. (B) The level of osteogenesis, chondrogenesis, and adipogenesis of ADSCs was assessed by ARS staining, Alcian blue staining, and Oil Red staining, respectively. Scale bar = 100 μm. (C) Immunostaining of Collagen II protein expression in ADSCs cultured on the PGMs and curcumin (5 uM) -loaded PGMs, respectively. Scale bar = 100 μm. (D) Relative expression of chondrogenic marker genes (COL2A1, SOX9, Aggrecan) after chondrogenic induction for 21 days (Mean ± SD; **p < < 0.01; biological replicates n = 3 per group).

Expression of collagen type II and aggrecan in cultured human articular chondrocytes. (a) Cells were labelled with polyclonal rabbit anti-human collagen type II and secondary antibody conjugated with Alexa Fluor 594 (red). (b) Cells were labelled with monoclonal mouse anti-human aggrecan and secondary antibody conjugated with Alexa Fluor 488 (green). The nuclei were visualized by Dapi dye (blue). Isotype controls had no staining (not shown).

TAP2 is localized in the chondrocytes and synoviocytes of arthritic joints of rats. FITC-conjugated TAP2 was delivered to the knee joints in rats (n = 3) on day 7 post-MIA injection. After 48 h, the knee joints were immunostained with (a) anti-collagen type II (chondrocytes) or (b) anti-Thy1 (synoviocytes). Scale bar = 100 μm (left). (c) The intensity of FITC-TAP2 staining was quantified in cartilages and synovium. The data are expressed as the mean ± SEM (one-way ANOVA test, ***p < < 0.001, **p < < 0.01 vs. D9).
