Cellular distribution and viability onto the alginate/bovine cartilage matrix tridimensional scaffold. (a) ADSCs retained in the scaffolds after 12 h and 5 and 10 days of cellularization, evaluated by fluorescence microscopy according to the number of nucleus stained with DAPI. (b) Quantitative image analysis: the data represent the average of 15 fields taken as 1.0, the number of cells at 12 h. (c) Alamar Blue cell viability assay of ADSCs and prechondrocytes in the biofunctionalized alginate scaffold at 0, 3, 5, and 7 days of culture ().
