摘要
目的 :探讨人血清白蛋白 (humanserumalbumin ,HSA)对人牙龈上皮细胞 (humangingivalepith elialcells,HGE)在种植体材料表面粘附作用的影响。方法 :HGE原代培养 ,免疫荧光染色法标记细胞 ,观察人牙龈上皮细胞在人血清白蛋白预孵育及普通纯钛试件表面的粘附。结果 :使用角朊细胞无血清培养基和分离酶成功地培养出HGE ;HGE经广谱细胞角蛋白单抗免疫组化染色为阳性 ;浓度为 5 0mg/ml的HSA预孵育于纯钛表面 ,4h时处理组粘附的HGE的数量显著少于对照组 ,12、2 4h处理组与对照组相比 ,粘附的细胞数量无显著性差异。结论 :HSA预孵育于纯钛表面 。
objective: To investigate the effect of human serum albumin(HSA)on the attachment of human gingival epithelial cells(HGEs)to commercial pure titanium(cpTi).Methods: HGEs were cultured, the cells of passage 2~5 were seeded on to cpTi samples which were preincubated in keratinocyte serum free medium with 50 mg/ml HSA or without HSA. Cell attachment was studied by immunofluorescence analysis.Results: HGEs were cultured and identified by positive expression of cytokeratin. 4,12 and 24 h after seeding attached cells on HSA preincubated cpTi were 218,730 and 849, those on the control 417,745 and 864, respectively.Conclusion: The early stage of cell attachment of HGEs on to cpTi may be inhibited by HSA.
