Question

Quizplus · Accepted Answer

Thrombopoietin (TPO),a hormone growth factor,is the main regulator of the circulating platelet mass,thus,a deficiency of TPO can lead to decreased platelets.
TPO is the factor necessary for platelet production; megakaryocytes are platelet precursors,so if they are elevated,the platelets would be as well.
Increased cell division would lead to increased platelets.
Platelets are produced in the bone marrow,not the spleen.
