- Bone morphogenetic protein 6 (BMP6) is an essential cytokine for the expression of hepcidin, an iron regulatory hormone secreted predominantly by hepatocytes. Bmp6 expression is upregulated by increased iron-levels in the liver. Both hepatocytes and non-parenchymal liver cells have detectable Bmp6 mRNA. Here we showed that induction of hepcidin expression in hepatocytes by dietary iron is associated with an elevation of Bmp6 mRNA in the non-parenchymal cells of the liver. Consistently, incubation with iron-saturated transferrin induces Bmp6 mRNA expression in isolated hepatic stellate cells, but not in hepatocytes. These observations suggest an important role of the non-parenchymal liver cells in regulating iron-homeostasis by acting as a source of Bmp6.
