Figure 3From: TGF-β1 conjugated chitosan collagen hydrogels induce chondrogenic differentiation of human synovium-derived stem cellsGrowth of hSMSCs cultured in hydrogels. (A) Bright field images of hSMSCs in the hydrogels. Scale bar = 200 μm. (B) Percentage area of cell clusters quantified by image analysis of bright field images. (*: p < 0.05 compared with MeGC and #: p < 0.05 compared with MeGC/Col, n = 3) (C) Proliferation of hSMSCs in hydrogels measured by CCK assay.Back to article page
