General Information

Thrombopoietin (TPO) is a glycoprotein hormone produced by the liver and kidney. It regulates the production of platelets and stimulates the production and differentiation of megakaryocytes.

TPO is used in the cell and gene therapy space for the ex vivo expansion and differentiation of HSCs.
