Abstract

In this study, based on a biomimetic approach, novel 3D biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. Macroporous chitosan/ gelatin/β-TCP scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. The results showed that the prepared scaffolds are highly porous, with porosities larger than 80%, and have interconnected pores. Biocompatibility studies were successfully performed by in vitro and in vivo assays. Moreover, the attachment, migration, and proliferation of chondrocytes on these unique temporary scaffolds were examined to determine their potentials in tissue engineering applications.
