Coloured TEM of a section through blood platelets
Bildnummer 11869757
| Active platelets. Coloured transmission electron micrograph (TEM) of a section through activated blood platelets. Platelet cells (thrombocytes) are formed in the bone marrow,and circulate in blood in large numbers. In an unactivated state they are round/oval,whereas activated platelets develop pseudopodia or extensions from the cell wall. Platelets contain cytoplasmic organelles such as mitochondria (green),endoplasmic reticulum and granules (dark blue). Platelets function in two ways: they plug defects in the walls of blood vessels,and are involved in clotting. They also release serotonin which constricts blood vessels.
