Platelets
Platelets are cell fragments produced from megakaryocytes.
platelets In vertebrates, cell fragments that bud off from the megakaryocytes in the bone marrow; carry chemicals needed for blood clotting. Cell fragment functioning in blood clotting.
yolk platelets - membrane-bound discs containing high concentrations of yolk found in eggs.
yolk plug - a patch of vegetal cells (endoderm) that remains exposed in the blastopore after the formation of the ventral lip during gastrulation.
The blood platelets (Fig. 456) are discoid or irregularly shaped, colorless, refractile bodies, much smaller than the red corpuscles. Each contains a central chromatin mass resembling a nucleus.
Platelets are important in wound healing, especially by quickly adhering to cut tissue and producing a healing blood clot.
Platelets result from cell fragmentation and are involved with clotting, as is shown by Figures 17 and 18. Platelets are cell fragments that bud off megakaryocytes in bone marrow. They carry chemicals essential to blood clotting.

Recent research has capitalized on the cloning of an important signalling receptor for collagen, glycoprotein VI, which is expressed only on platelets, ...
Every human cell (except for red blood cells and the platelets that are critical to normal blood clotting and wound healing) contains a discrete nucleus that has within the roughly 6 feet of a special chemical called deoxyribonucleic acid, or DNA.

An example of a multipotent stem cell would be the hematopoietic stem cell, which can give rise to all the blood lineages, including white blood cells, leukocytes, lymphocytes, the platelets, the red blood cells, and macrophages.
The specialized cells in our blood are the red blood cells (rbcs) containing the respiratory protein, hemoglobin, to carry gases, the white blood cells (e.g., phagocytes, lymphocytes) which fight infection and the blood platelets which upon ...
