Hepatic hematopoietic islets and vasculature. Liver sections from T241-VEGF and T241-vector tumor-bearing mice were stained with H&E (A and B), an anti-Ter119 antibody (C and D), or anti-CD31 antibody (E and F). Arrows in panels A, C, and D point to hematopoietic islets. Arrows in E and F point to hepatic sinusoidal microvessels. CV = central vein. HC = hepatocyte. Bar in panels A-D = 100 μm. Bar in panels E and F = 50 μm.
