摘　　要：为探讨增进牙龈上皮细胞在钛表面附着的因素 ,将基底膜提取物 Matrigel涂在光滑纯钛片表面 ,扫描电镜观察原代培养的人牙龈上皮细胞在涂 Matrigel钛表面和光滑钛表面的伸展情况。结果发现 ,细胞培养第 3d和 6 d时 ,涂 Matrigel组细胞在钛表面贴附伸展明显较对照组好 ,表明此基底膜提取物 Matrigel有促进人牙龈上皮细胞在钛表面贴附的作用。In order to investigate the factors which could enhance the integrity of the biological seal between implant and epithelial cells, basement membrane matrigel was coated on the surface of smooth pure titanium. SEM observations showed that the spreding of primary cultured human gingival epithelial cells on Matrigel coated titanium surface was better than that of control groups on the third and the sixth day. This result suggests that the attachment of human gingival epithelial cells to titanium can be enhanced by the basement membrane matrigel.\;
