platelet formation
Definition
Target type: biologicalprocess
The process in which platelets bud from long processes extended by megakaryocytes. [GOC:mah, ISBN:0815316194]
Platelet formation, also known as thrombopoiesis, is a complex process that begins in the bone marrow and involves the differentiation and maturation of megakaryocytes, large polyploid cells. Megakaryocytes are derived from hematopoietic stem cells, which undergo multiple rounds of DNA replication without cell division, resulting in cells with a large nucleus and multiple sets of chromosomes. Megakaryocytes then extend proplatelet processes, long, thin cytoplasmic extensions that contain microtubules and actin filaments. These proplatelet processes fragment into small, membrane-bound platelets, which are released into the bloodstream. Platelet formation is tightly regulated by various growth factors, including thrombopoietin (TPO), which stimulates megakaryocyte proliferation and maturation. Other factors, such as interleukin-3 (IL-3), interleukin-11 (IL-11), and stem cell factor (SCF), also contribute to megakaryopoiesis. During the process of platelet formation, megakaryocytes undergo a series of morphological changes. They become larger, their cytoplasm becomes more granular, and they develop a characteristic lobulated nucleus. These changes are driven by the expression of specific genes, including those encoding for platelet-specific proteins, such as alpha-granules, dense granules, and the platelet membrane glycoproteins. Once mature platelets are released from the bone marrow, they circulate in the bloodstream for 7-10 days. These platelets play a crucial role in hemostasis, the process of blood clotting. They adhere to the site of injury, forming a platelet plug that helps to stop bleeding. They also release factors that activate the coagulation cascade, leading to the formation of a fibrin clot that reinforces the platelet plug. Platelet formation is essential for maintaining normal blood clotting and preventing excessive bleeding.'
