FABP3 and neoplasm: Moreover, the intracranial U87MG‐MDGI‐GFP xenografts grew invasively (Fig 2A and B), formed secondary tumours (diameter > 300 μm) in the brain (Fig 2C, D and G) and displayed vascular co‐option (angiotropic tumours with diameter < 300 μm, Fig 2E, F and H) unlike the control GFP‐expressing U87MG‐derived xenografts that only formed well‐delineated masses.
