Mast cells, light micrograph

Mast cells. Light micrograph of several mast cells (pink rounded objects). These leucocytes (white blood cells) contain the chemical mediators histamine, serotonin and heparin. Part of the immune system, they release their contents during a localized inflammatory immune response to invading pathogens and during an allergic reaction. Heparin is an anticoagulant which prevents abnormal clotting. Histamine and serotonin cause the symptoms of allergies

EDITORS COMMENTS
This print showcases a light micrograph of mast cells, which are depicted as pink rounded objects. These remarkable leucocytes, also known as white blood cells, play a crucial role in our immune system. They contain chemical mediators such as histamine, serotonin, and heparin. Histamine and serotonin are responsible for triggering the symptoms associated with allergies. When our body encounters allergens or invading pathogens, these mast cells release their contents during an allergic reaction or localized inflammatory immune response. This process helps to protect our body from harmful substances. Additionally, heparin found within mast cells acts as an anticoagulant that prevents abnormal clotting in our circulatory system. It ensures smooth blood flow and maintains healthy circulation throughout the human body. The intricate details captured by this light microscope image provide valuable insights into cell biology and histology. It highlights the cellular complexity involved in immunological processes and haematological functions within our bodies. This stunning photograph is a testament to the incredible capabilities of science photography from Science Photo Library. It serves as a reminder of how microscopic elements like mast cells contribute significantly to maintaining normal bodily functions while defending against potential threats.
