| 摘 要： | 目的：探讨人牙韧带成纤维细胞与壳聚糖—磷酸三钙复合材料的生物和容性。方法：采用冷冻干燥法制备壳聚糖-磷酸三钙复合材料，组织块法培养人牙周韧带细胞，传代扩增后接种到材料上，体外继续培养，扫描电镜观察。结果：扫描电镜下可见材料具有良好的多孔网状结构，人牙周韧带细胞伸出多个伪足样突起，紧密贴附在材料表面，细胞沿材料的孔隙边缘生长并连接成片。结论：人牙周韧带成纤维细胞与壳聚糖-磷酸三钙复合材料具有良好的生物相容性。

| Abstract: | AIM:To study the biocompatibility of human periodontal ligament cells and chitosan/tricalcium phosphate (CTCP).METHODS:The CTCP was prepared by freeze-drying. Human periodontal ligament cells (hPDLC) cultured in vitro were collected and seeded on the CTCP. The cell growth in CTCP was observed by scanning electronic microscopy (SEM).RESULTS:SEM showed the porous structure of the CTCP and the seeded hPDLCs were well attached to the CTCP with cytoplasmic extensions and lamellipodia. CONCLSUION:The hPDLCs have a biocompatibility with CTCP. |
