Metabolomic Analysis of Liver Tissue from the VX2 Rabbit Model of Secondary Liver Tumors

Figure 2

Microscopic morphology of VX2 tumors. All implanted tumor grafts showed macroscopic growth on liver sites. At histology, most tumors had a pseudocapsule formed by fibrotic tissue that surrounded the tumor which contained typical epithelial cells with malignant morphology without neoangiogenesis, tumor invasion, or lymphocyte infiltration at this stage of tumor growth (panel ×20).
