| Abstract: | Objective To investigate the effects of three- dimensional culture of seeding chondrocytes encapsulated in collagen gel into BCM scaffolds on the growth and function in vitro. Methods Chondrocytes encapsulated in collagen gel were incorporated into BCM scaffold, then the status of adhesion, growth and proliferation of the cells were observed by phase- contrast and scanning electron microscope. Chondrocytes- scaffold complexes were cultured for 14 days and evaluated by histological analysis. Results Chondrocytes were able to attach, grow and proliferate well on the scaffolds and chondrocytes - scaffold complexes can form mature cartilage tissue after 14 days culture in vitro. Conclusion Combination collagen gel with BCM exhibits excellent cell biocompatibility and can be used as a vehicle for growth factors. |
