Standard histology of MNNG-HOS tumour. Standard histology with hematoxylin-eosin staining confirming the rich vascularisation of the tumours with capillaries originating from the CAM (arrows in A and B). The tumours also contain stromal cells with disseminated monocytes. Areas of angiogenesis (arrowheads in B and C), necrosis and haemorrhage (asterisks in C) are present. A: Macroscopic picture, B: HE 10× (scale bar 100 μm), C: HE 40× (scale bar 50 μm).
