Platelet or thrombocyte SEM

Platelet or thrombocyte SEM

Newly formed platelet or thrombocyte after megakaryocyte fragmentation in the red bone marrow and spleen. Mature activated platelets have numerous cytoplasmic extensions and channels of the open canalicular system. Each megakaryocyte produces and releases hundreds of platelets into the circulatory system and nearly a trillion platelets circulate in an adult human and respond to blood vessel injury by changing shape, secreting granule contents, and aggregating, thus playing an essential role in blood clotting and wound repair. They also activate certain immune responses. SEM X5335.
