Fig. 6From: Synergistic interaction of hTGF-β3 with hBMP-6 promotes articular cartilage formation in chitosan scaffolds with hADSCs: implications for regenerative medicineImmunofluorescence staining of aggrecan (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
