Figure 7. Cirrhosis induction.
(A) Trichrome stained Oncopig liver 8 weeks following cirrhosis induction shows irregular and morphologically effaced hepatic lobules circumferentially surrounded by thick fibrous septa (arrowheads) consistent with stage 4 liver fibrosis (cirrhosis; scale bar 600 μm). (B) Trichrome stain of normal Oncopig control liver shows morphologically non-expanded portal tracts maintaining their usual hexagonal distribution, without cetrilobular venular and sinusoidal thickening (scale bar 600 μm).
