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.
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.
Physical form
Lyophilized from 10 mM Tris, pH 8.0.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/mL. 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.

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.
