optimum results were obtained with chitosan hydrogel fragments of 55-70% DD and
1.5% chitosan.
9.5.3.2 Chitosan-Based Porous Hydrogels-Chondrocytes Construct
Chondrogenesis has been described on chitosan scaffolds. Since cartilage is avascular, car-
tilage nutrition, and metabolism are mainly influenced by local diffusion and cell-matrix
