From: In vitro study on human cytomegalovirus affecting early pregnancy villous EVT's invasion function
The expression of MMP-2 protein in two groups' villous explants. A, B. In the villus of two groups, MMP-2 protein expressed mainly in EVT endochylema and little in VT, ST and interstitial substance; C. According to the comparison of average optical density of two groups' MMP-2 protein expression, the protein expression significantly decreased in infected group(P < 0.01); D. Western blot method was used to detect MMP-2 protein of two groups' villus and the protein was detected at 72kDa; E. In infected group, MMP-2 protein expression level reduced(P < 0.05). Above these experiments were repeated 3 times.
