The dynamics of the hematogenous microcirculation of the CAM (as seen in this video) is a big reason why we use this model to understand cancer cell extravasation and cancer microparticle (extracellular vesicle) biogenesis. To get the blue nuclei, I injected diluted Hoechst. To get the endothelial/vessel walls, I injected LCA lectin-FITC. To get the lumen, I injected 70kDa Alexa555-Dextran. The merge panel (top) beautifully shows all the components in this highly active microcirculation environment. Paper to come out on this very soon.
