Fig. 4. Lipid accumulation in hepatocytes is impaired in
LAP-tTA/TRE-VEGFR2T mice. (A,B) Oil Red O staining of liver
sections reveals decreased hepatocellular lipids in mutant livers (B) when
compared with littermate control livers (A). Samples are counterstained with
Hematoxylin. (C,D) Infusion experiment with DiI-labeled remnant lipoproteins
demonstrates the quick and efficient uptake and transportation of serum lipid
by hepatocytes in control livers (C) but not in mutant livers (D). (E,F)
Anti-APOE staining shows continuous APOE accumulation in the space of Disse of
control livers (E), whereas, in the mutant livers, an area with little or
disrupted APOE distribution is evident (F).
