Fig. 8From: Selective deletion of hepatocyte platelet-derived growth factor receptor α and development of liver fibrosis in miceAssessment of PDGFRα expression in the human liver with hepatitis without liver fibrosis. a Immunohistochemistry of liver specimens with hepatitis showed the presence of PDGFRα at the hepatocyte membrane (arrows) and in nonparenchymal cells (arrowheads), whereas normal-liver specimens showed no PDGFRα staining. Original magnification, × 400. b Whole-cell lysates from pathologically proven hepatitis tissue without significant fibrosis (n = 7) were examined for col1α(I) and PDGFRα mRNA levels compared to those in normal liver tissue (n = 7)Back to article page
