Weibel Palade Bodies

Excerpt

Weibel-Palade bodies are small storage granules located in endothelial cells comprising the intima of the heart and blood vessels. They are found in arteries, capillaries, veins, and the endocardium, but notably not in the lymphatic vessels. These bodies function to store 2 principal molecules, P-selectin and Von Willebrand factor. These 2 agents play a role in inflammation and hemostasis.
