Fig. 7From: Synergistic interaction of hTGF-β3 with hBMP-6 promotes articular cartilage formation in chitosan scaffolds with hADSCs: implications for regenerative medicineImmunofluorescence staining of collagen type II (green) at day 7, 14 and 28 in chitosan scaffolds with hADSCs cultured in normal (NS), standard chondrogenic (CS) or modified chondrogenic + hBMP-6 medium (CS + hBMP-6) . The chitosan scaffolds fluoresced yellow, whereas living cell nuclei fluoresced blue. Magnification set a 10xBack to article page
