ResumoBone morphogenetic protein-6 (BMP-6) is produced by bone marrow-mesenchymal (BMSC) and hematopoietic stem cells, which can differentiate into bone, cartilage, adipose, muscle, hematopoietic, synovial and other tissues. Bmp6-/- null mice have low hepcidin serum levels and an iron overload, resembling hereditary hemochromatosis, which may cause a reduced number of pancreatic beta-cells, increased serum glucose and diabetes. BMP-6 circulates in the normal human plasma and is produced by BMSC prior to differentiation into osteoblasts. Moreover, it is also released by osteoclasts as a key bone coupling factor recruiting osteoblasts to the resorption site. Due to unique structural, receptor binding and signaling characteristics much smaller amounts of BMP-6 than BMP-7 are needed in vivo to induce regeneration of bone defects in animals.
