Figure 1From: Tumour-associated endothelial-FAK correlated with molecular sub-type and prognostic factors in invasive breast cancer Immunofluorescence Analysis of FAK expression in invasive breast tumour epithelium and endothelium of different ‘Intrinsic’ molecular tumour types. Formalin fixed paraffin embedded tissue was stained for Pecam-1 (red) to identify endothelial cells and for FAK (green). Cell nuclei have been identified by counterstaining with DAPI. Characteristic examples are shown from Luminal A (A–D), Luminal B (E–H), Her2-overexrpessing (I–L) and Triple Negative (M–P) invasive breast tumours. All images are on x40 magnification. The analysed vessels had a diameter ≥5 μm and vessels in a ≥100 μm distance away from the tumour cell margins have been excluded. Arrows indicate tumour cells and arrowheads analysed blood vessels.Back to article page
