General description
TPO (thrombopoietin) is a hematopoietic cytokine expressed in multiple tissue types. It is predominantly produced by liver and kidney and acts as a ligand for the cell surface receptor c-mpl.
TPO is a lineage specific growth factor, produced in the liver, kidney and skeletal muscle. It stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the c-mpl receptor and acts as an important regulator of circulating platelets. Human and murine TPO exhibits cross-species reactivity. Recombinant murine TPO is a fully biologically active 174 amino acid polypeptide (18.7 kDa), which contains the erythropoietin-like domain of the full length TPO protein.
Biochem/physiol Actions
TPO (thrombopoietin) is the key regulator of thrombopoiesis for platelet lineage. In both mice and humans, inactivation of this gene results in significant decrease in number of mature platelets produced by marrow progenitors. Transgenic mice with increased expression of this protein show progressive fibrosis and osteosclerosis of the bone marrow, as well as histological changes in kidneys, leading to mesangioproliferative glomerulopathy.

Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of ?0.5 mg/ml. Slow to dissolve. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Platelet production is regulated primarily by the cytokine thrombopoietin (TPO). Although TPO is expressed in several different tissues, only in the bone marrow has the level of expression been reported to increase in response to reduced numbers of platelets. In

We previously reported that mice transgenic (Tg) for thrombopoietin (TPO) developed progressive fibrosis and osteosclerosis of the bone marrow. Here, we show that TPO-overexpressing mice also exhibited notable histological changes in the kidneys, including an increased number of mesangial cells

Hematopoietic stem cell (HSC) self-renewal and multilineage reconstitution are controlled by positive and negative signaling cues with perturbations leading to disease. Lnk is an essential signaling adaptor protein that dampens signaling by the cytokine thrombopoietin (Tpo) to limit HSC expansion.
