摘要

目的:研究肝细胞生长因子（HGF）、碱性成纤维细胞生长因子（bFGF）在新鲜和两种保存羊膜中的表达

探讨新鲜和保存羊膜的生物学活性差异。方法:取健康剖宫产产妇胎盘羊膜

随机分成三组:新鲜组、DMEM/甘油-80℃保存组、纯甘油4℃保存组（保存1、3个月）

应用免疫组织化学方法

检测HGF、bFGF在各组羊膜中的表达。结果:HGF、bFGF主要分布于羊膜上皮层。HGF在DMEM/甘油组和纯甘油组保存1、3个月时的表达明显低于新鲜羊膜组

统计学上差异有显著性（P<0.0001）

bFGF在两组保存3个月时的表达明显低于新鲜羊膜组

统计学上差异有显著性（P<0.01）。结论:羊膜经DMEM/甘油-80℃、纯甘油4℃保存后

HGF、bFGF减少

并随保存时间的延长活性逐渐下降。

Abstract

Objective:To study the expressions of hepatocyte growth factor (HGF) and basic fibroblast growth factor (bFGF) in fresh and two preserved amniotic membranes (AM)

and to explore their biological vitality.Methods:The amniotic membranes from the healthy puerperia with abdominal delivery were randomly divided into three groups:fresh group

DMEM/glycerol preserved group at -80℃ and glycerol preserved group at 4℃ (for 1 and 3 months).Immunohistochemical method was used to investigate the changes in the expressions of HGF and bFGF among the three groups.Results:HGF and bFGF were distributed in the epithelium of AMs mostly.The expressions of HGF in both preserved AMs for 1 and 3 months decreased significantly compared with fresh AM (P<0.0001)

and the expressions of bFGF in both preserved AMs for 3 months decreased significantly compared with fresh AM (P<0.01).Conclusion:HGF and bFGF both decrease in AMs preserved in DMEM/glycerol at -80℃ and in glycerol at 4℃

and their vitality declines gradually with preserving time.
