Immunohistochemical hepatic expression of MMP-7. Immunohistochemical staining of MMP7 of cases with neonatal cholestasis (red arrow points to bile duct): A A case of PFIC showing negative expression of MMP7 in hepatocytes with focal apical staining in the bile duct (IHC × 200). B A case of bile inspissation showing mild expression of MMP7 in both parenchyma and bile ducts (IHC × 200. C A case of BA showing moderate expression of MMP7 in both parenchyma and bile ducts (IHC × 200). D A case of BA showing strong expression of MMP7 in both parenchyma and bile ducts (IHC × 200)
