Which Platelets Are Produced?

Platelets are made in our bone marrow, the sponge-like tissue inside our bones. Bone marrow contains stem cells that develop into red blood cells, white blood cells, and platelets. Platelets and other blood components are always needed.

Where are platelets produced and destroyed?

Under conditions of TCP, the spleen and liver are the sites for accelerated platelet destruction, and in thrombocytosis, the spleen can become a supplemental breeding ground for megakaryocytes, in addition to the bone marrow space. Humans produce and remove 10¹¹ platelets per day.

Does the liver produce platelets?

Given their crucial role in blood coagulation and thrombosis, platelets are mainly produced by the liver during foetal life. After birth, the bone marrow becomes the most important source of platelets, where they develop from progenitor cells named megakaryocytes.
