Does intrauterine exposure to high saturated fat diet elevate risk of adult-onset chronic diseases in C57BL/6 mice?
Collectively, these data suggest that offspring of dams who consume a diet rich in saturated fats during pregnancy are at increased risk of adult-onset chronic disease. Additionally, these chronic diseases were determined to be in-part OS-mediated, and preventable by increasing a prenatal dietary antioxidant; this knowledge offers both a putative mechanism of disease pathogenesis and suggests a potential preventive strategy.
Type I collagen-producing cells do not originate from hepatocytes. Hepatocytes in vivo neither acquire mesenchymal marker expression nor exhibit a morphological change clearly distinguishable from normal hepatocytes. Our results strongly challenge the concept that hepatocytes in vivo acquire a mesenchymal phenotype through EMT to produce the ECM in liver fibrosis.
