Platelet-derived products have different effects on HUVEC tube formation on Matrigel (A). Representative images of the tube formation experiment after 6 h of incubation with control medium (heparin), or platelet-derived products. Scale bars = 300 µm. Arrows indicate platelets attached to the endothelial lining of the pseudo-vascular structure (B). Graph shows the average area without cells relative to the total area., ** p-value < 0.01, **** p value < 0.0001 compared to control cultures.
