摘要: 目的:检测磷酸三钙(TCP)/壳聚糖支架在动物实验中是否适合培养牙周膜干细胞(PDLSC)。方法:制作3种不同比例TCP/壳聚糖支架,加入PDLSC和TCP/壳聚糖支架混合培养24 h后植入裸鼠背部皮下,4周后切取移植物,HE染色和Ⅰ型胶原(Col-Ⅰ)免疫组化染色,镜检。结果:PDLSC在TCP/壳聚糖支架上生长良好,TCP/壳聚糖支架比单纯壳聚糖支架降解率减低,3组支架均有Col-Ⅰ生成。结论:TCP/壳聚糖支架适合培养PDLSC。

Abstract: Objective: To test TCP/Chitosan scaffold that PDLSC were cultuled. Methods: We prepared three kinds of TCP/Chitosan scaffolds, cultured PDLSC on TCP/Chitosan scaffold for 24 hrs, and then transplanted it subcutaneously into athymic mice. Implants were taken out after 4 weeks and stained by HE and Col-Ⅰ. Then we observed them by lightscope. Results: PDLSC grow well on TCP/Chitosan scaffold. Degradation rate of TCP/Chitosan scaffold was lower than pure Chitosan scaffold. Col-Ⅰ was observed in three kinds of scaffolds. Conclusion: TCP/Chitosan scaffold is good for culturing PDLSC.

Key words: PDLSC, TCP , Chitosan, Col-Ⅰ
