Bone morphogenetic protein 4 (BMP4), also known as Bone morphogenetic protein 4 (BMP-4), Bone morphogenetic protein 2B (BMP-2B), and encoded by the gene name BMP4/ BMP2B/ DVR4, is morphogenetic protein that induces cartilage and bone formation. Similar to other bone morphogenetic proteins, BMP4 has been shown to play an important role in bone and cartilage development, specifically tooth and limb development and fracture repair. It has been shown to be involved in muscle development, bone mineralization, and uteric bud development. BMP4 has also been implicated in Fibrodysplasia Ossificans Progressiva. In human embryonic development, BMP4 is a critical signalling molecule required for the early differentiation of the embryo and establishing of a dorsal-ventral axis. BMP4 is secreted from the dorsal portion of the notochord, and it acts in concert with sonic hedgehog (released from the ventral portion of the notochord) to establish a dorsal-ventral axis for the differentiation of later structures. BMP4 stimulates differentiation of overlying ectodermal tissue. Inhibition of the BMP4 signal (by chordin, noggin, or follistatin) causes the ectoderm to differentiate into the neural plate. If these cells also receive signals from FGF, they will differentiate into the spinal cord; in the absence of FGF the cells become brain tissue.，官网链接：https://www.sigmaaldrich.cn/product/mm/mabd411 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
