Question

The processes of megakaryocytes from which platelets are derived, extend between endothelial cells of blood vessels and are called .

Answer 1

The cytoplasmic fragments of the megakaryocytes constitute the platelets, this fragments simultaneously into thousands of new platelet cells, these morphological changes are known as proplatelets.

What are proplatelets?

They are cytoplasmic protrusions from which platelets or fragments are going to be detached that end up maturing in the circulation.

Characteristics of proplatelets

• Platelets are formed from the fragmentation of giant cells, which emit cytoplasmic protrusions.

• Each megakaryocyte has about 6 proplatelets, and each proplatelet houses about 8,000 platelets, these "bags" full of platelets enter the bloodstream where they break, releasing them.

Therefore, we can conclude that the megakaryocytes form the future platelets, these platelets are grouped in cytoplasmic portions, called proplatelets.
