[Preliminary study on chitosan/HAP bilayered scaffold].

Objective: To study repair of osteochondral defects by using composite of autologous BMSCs and chitosan/HAP (CS/HAP) bilayered scaffold in rabbits and its feasibility as osteochondral tissue engineering scaffolds.

Methods: CS/HAP bilayered scaffolds were produced with CS and HAP using a lyophilization and sintering method. The pore size of the scaffold was observed by scanning electron microscopy (SEM).
