Abstract:
PURPOSE: To confirm the adhesion and matrix formation of chondrocytes which were cultured on chitosan beads and to elucidate the difference between the porous chitosan beads and non-porous chitsan beads as scaffold for chondrocytes. MATERIALS AND METHODS: Chondrocytes isolated from rabbit articular cartilage were cultured in vitro on porous and non-porous chitosan bead for 2 weeks. Histochemical (H&E stain, Toluidin blue stain) and scanning electromicroscopic approaches were used to compare the differences between two groups. RESULTS: In both groups, adhesion and proliferation of chondrocytes were observed on scanning electron microscopy. which were more active in the porous chitosan bead group. On histochemical staining with toluidine blue, the porous chitosan bead group showed stronger metachromasia than that of the non-porous chitosan bead. CONCLUSION: It is concluded that both chitosan beads could work as an effective scaffold for culturing chondrocytes, and that porous chitosan bead may be a better scaffold than non-porous chitosan bead because of cavities in former bead.
