摘要 目的探讨人重组骨形成蛋白-4(rhBMP-4)对人牙周膜成纤维细胞生长增殖及分化的影响。方法选取因正畸需要拔除的第一前磨牙,刮取根中1/3牙周组织作为标本,采用牙周膜细胞体外培养技术培养牙周膜成纤维细胞,将浓度为5,10,20,40ng/ml的rhBMP-4与牙周膜成纤维细胞共同培养5d,用MTT法测定细胞增殖情况,用碱性磷酸酶试剂盒检测牙周膜成纤维细胞碱性磷酸酶的活性。结果第1,3,5天,5—20ng/ml的rhBMP-4对牙周膜成纤维细胞的生长增殖能力及碱性磷酸酶活性的影响与对照组比较差异均有显著性(P〈0.05)。结论在一定时间范围内,rhBMP-4对牙周膜成纤维细胞生长增殖及分化有促进作用。
