No, platelets are relatively small (2-4 microns) and are anucleate.
Platelets are non-nucleated because they are actually fragments of larger cells called megakaryocytes, which are found in the bone marrow. During their formation, the megakaryocytes undergo a process called endomitosis, where they replicate their DNA without cell division, resulting in large cells that then release small cytoplasmic fragments into the bloodstream. This lack of a nucleus allows platelets to be more flexible and specialized for their primary functions in hemostasis and clot formation. Additionally, their non-nucleated nature contributes to their short lifespan, as they lack the machinery for protein synthesis and cellular repair.
red blood cells that have not lost their nucleus.
The large cells that produce platelets are called megakaryocytes.
Macrothrombocytes are unusally large platelets.
Platelets are produced in the bone marrow by large cells called megakaryocytes.
Unusually or comparatively large in size or dimensions.
no they are not all nucleated
Large cells in the bone marrow are typically referring to the megakaryocytes, which are responsible for producing platelets. Platelets play a crucial role in blood clotting and wound healing. Abnormalities in the production or function of these large cells can lead to bleeding disorders.
RBCs in reptiles are nucleated.
Myeloid stem cells
Platelets are formed from large cells called megakaryocytes. Megakaryocytes undergo a process called cytoplasmic fragmentation to produce platelets, which are involved in blood clotting.
No, platelets do not have a nucleus. They're known as anucleur cells.
