  Bone Morphogenetic Protein
Bone Morphogenetic Proteins have recently been determined to mediate neural crest inductions and migration in chick embryos.
After neural induction, these BMPs can promote migration of neural crest from the neural tube and activate neural crest markers such as slug.
Links between Hox genes and BMP in neural crest induction are also being investigated.

 bmp2b - bone morphogenetic protein 2b
Bone patterning is altered in the regenerating zebrafish caudal fin after ectopic expression of sonic hedgehog and bmp2b or exposure to cyclopamine.
We have previously shown that the maternal effect dorsalization of zebrafish embryos from sbn(dtc24) heterozygous mothers is caused by a dominant negative mutation in Smad5, a transducer of ventralizing signaling by the bone morphogenetic proteins Bmp2b and Bmp7.
At higher temperature, the phenotype of snh(ty68) mutant embryos is identical to that caused by the amorphic bmp2b mutation swirl swr(ta72) and similar to that caused by the smad5 mutation somitabun sbn(dtc24).

 NASS-New Technologies-Bone Morphogenetic Protein   (Site not responding. Last check: 2007-10-16)
In spine surgery, especially during spinal fusions, surgeons may opt to use transplanted bone grafts to aid in the healing and remodeling of the spine after surgery.
The use of bone grafts can add increased postoperative pain, if the bone is transplanted from one area of the patient's body to another (called autograft), or a chance of disease transmission if the bone is transplanted from one person to another (called allograft).
Spine surgeons hope the use of BMP and rhBMP (BMP that is produced in a laboratory) may someday aid them in generating and repairing bone without the drawbacks of grafts.

 [No title]
Bone morphogenetic protein 7 is broadly efficacious in renal osteodystrophy, and importantly increases the skeletal deposition of ingested phosphorus and calcium, improving ion homeostasis in chronic kidney disease.
Bone morphogenetic protein 7 was shown to prevent vascular calcification in a model of chronic kidney disease associated with the restoration of osteocalcin expression to normal tissue-restricted sites.
SUMMARY: Bone morphogenetic protein 7 may be a powerful new therapeutic agent for chronic kidney disease, with the novel attribute of not only treating the kidney disease itself, but also directly inhibiting some of the most important complications of the disease state.

Bone morphogenetic proteins are dimeric molecules with two chains held together by one disulphide bond.
The standard method for assaying BMP is its intramuscular implantation into a mouse or rat and the estimation of new bone induction by radiology and histology (Urist & Strates 1971).

 Baumer S.A.
BMP is the English abbreviation to Bone Morphogenetic Proteins and was firstly described buy Marshal Urist in 1960 (11).
BMP and other growing bone factors can be found in small quantities in several locations such as mesenchymal and periosteum cells, bone matrix collagen fibers and also in small non-collagen cells of the bone matrix.
BMP are in part distinct from other bone growing factors because they act by inducing the differentiation of mesenchymal cells into chondroblasts and osteoblasts and not increasing the mitotic activities of cells.

 Bone morphogenetic protein signaling during chondrocyte maturation.
Endochondral bone formation is a multistep process involving chondrocyte proliferation, hypertrophy, calcification, degradation and replacement of cartilage by bone.
Deletion of a 180bp region from the 533bp region abolished all BMP responsiveness; however, this fragment alone was unable to confer BMP responsiveness, suggesting multiple elements may be responsible for BMP regulation of this gene.
The effects of BMPs on USCs could be mimicked by retrovirally expressing a constitutively active BMP receptor type IB (CA-IB) and blocked with a dominant negative receptor type IB.
