Fibrin mesh. Coloured scanning electron micrograph (SEM) of a mesh of the protein fibrin in a blood clot. The production of fibrin is triggered by cells called platelets, activated when a blood vessel is damaged. The fibrin binds the various blood cells together, forming a solid structure called a blood clot.
