From: The biological function of type I receptors of bone morphogenetic protein in bone
Regulatory roles of ALK2, ALK3, and ALK6 in the various differentiation stages of osteolineage, chondrolineage, and osteoclast lineage cells and myoblasts. Osteoblasts, chondrocytes, and myoblasts are derived from mesenchymal progenitor cells, whereas osteoclasts are derived from hematopoietic precursors. BMP, bone morphogenetic protein.
