Expressions of tissue factor and tissue factor pathway inhibitor in the atherosclerotic plaque / 基础医学与临床

ABSTRACT

Objective To observe the expression and location of TF and TFPI in femoral artery atherosclerotic plaque.Methods We detected the expressions and locations of TF and TFPI in femoral artery atherosclerotic plaque by immunohistochemical and double-stain immunohistochemical method.We detected TF mRNA and TFPI mRNA expressions in atherosclerotic plaque by RT-PCR,with the normal umbilical artery as a control.ResultsThe normal umbilical artery contained little TF,TFPI and their mRNA in the adventitia.A great deal of TF,TFPI and their mRNA were found in the tunica intima of the femoral artery atherosclerotic plaque.Conclusion Expression of TF,TFPI and their mRNA of all types of cells and stroma in the proliferative tunica intima.
