Comparative study on the expressions of HGF and bFGF between fresh and preserved amniotic membranes / 重庆医科大学学报

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 groupsfresh 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
