The precursor cell to blood platelets are megakaryocyte precursor (MkP) cells in the bone marrow.
red bone marrow
Fragments of a large precursor cell (a megakaryocyte) found in the bone marrow. These fragments adhere to areas of blood vessel damage and release chemical signals that direct the formation of a blood clot.
Thrombopoietin is the hormone that stimulates platelet production by acting on bone marrow cells that ultimately become platelets.
You find bone marrow in the middle of your bones. Marrow is made of spongy cells.
Thrombocytes, also known as platelets, are primarily formed in the bone marrow. They are produced from large cells called megakaryocytes, which break apart into smaller platelet fragments that are released into the bloodstream to help with blood clotting.
Bone marrow
Since Bone marrow produces blood cells, if bone marrow is destroyed WBCs, RBCs and platelets will not be formed. However there are no bones and therefore no bone marrow in plants.
Either an infection is active or you have cancer or you have a problem with the bone marrow or you are bleeding
