Objective: To establish a three-dimensional cultured model of dog periodontal ligament cells(PDLC),and therefore to evaluate the feasibility of chitosan/tricalcium phosphate(CTCP)as the scaffolds of periodontal tissue engineering.

• 目的:建立狗牙周膜细胞(PDLCs)体外三维立体培养模型,探讨以狗PDLCs为种子细胞,以壳聚糖-磷酸三钙复合体为支架材料应用于牙周组织工程的可行性。
