Figure 5From: TGF-β1 conjugated chitosan collagen hydrogels induce chondrogenic differentiation of human synovium-derived stem cellsH & E staining of hSMSCs cultured in hydrogels at days 7, 14, 21 in culture. The encapsulated cells maintained round cell morphology throughout the culture periods. The cell aggregations were additively promoted with Col II and TGF-β1 supplementations. Scale bar = 100 μm.Back to article page
