Type I receptors for bone morphogenetic proteins (BMPs), i.e., BMPR‐IA and BMPR‐IB, are transmembrane serine/threonine kinases, that bind osteogenic protein‐1 (OP‐1, also termed BMP‐7) and BMP‐4. Using antibodies specific to BMPR‐IA and ‐IB, we have studied the expression of BMP type I receptors in the bone formation process during embryonic development and fracture healing. In the mouse embryo, both BMPR‐IA and ‐IB were expressed in condensing mesenchymal cells at 13.5 days post coitum (p.c… 

The biological function of type I receptors of bone morphogenetic protein in bone

This review focuses on all three types of BMPRI, which consist of activin-like kinase 2 (ALK2, also called type IA activin receptor), activin/threonine kinase 3 (ALK3,Also called BMPRIA), and Activin- like kinase 6 (ALK6), and the current progress regarding the roles of these receptors during myogenesis, chondrogenesis, and osteogenesis.

Distinct roles of type I bone morphogenetic protein receptors in the formation and differentiation of cartilage.

It is demonstrated that the two type I BMPRs, BM PR-IA and BMPR-IB, regulate distinct processes during chick limb development and regulates apoptosis.

Bone morphogenetic protein receptor signaling is necessary for normal murine postnatal bone formation

The effects of alterations in BMP receptor function targeted to the osteoblast lineage are shown and a necessary role of B MP receptor signaling in postnatal bone growth and bone formation in vivo is demonstrated.

BMP signaling components are expressed in human fracture callus.

Up‐regulation of bone morphogenetic protein receptor IB by growth factors enhances BMP‐2‐induced human bone cell functions

Examination of the effects of TGF‐β1, FGF‐2, and PDGF‐AB on BMPR expression and BMP‐2‐mediated osteoblast functions in primary human bone cells suggests that they might positively modulate bone formation by up‐regulating BMPR‐IB in vivo.

Expression of Bone Morphogenetic Protein-6 and Bone Morphogenetic Protein Receptors in Myoepithelial Cells of Canine Mammary Gland Tumors

Findings suggest that the expression of BMP and its receptors on the myoepithelial cells might play a role in the ectopic cartilage formation in canine mammary gland tumors, especially in benign mixed tumors.

Bone morphogenetic protein receptors and their nuclear effectors in bone formation

Pioneering studies on the ability of extracts from decalcified bone matrix to promote ectopic bone and cartilage formation [1] led to searches for the identity of these morphogens which define

Expression of bone morphogenetic proteins and rat distal-less homolog genes following rat femoral fracture

Findings indicate that BMP-4 and rDlx are selectively expressed following femoral fracture in the rat, and suggest that they are involved in the formation of the callus at an early point during the postfracture healing of bone.

Bone Morphogenetic Protein Receptor IB Signaling Mediates Apoptosis Independently of Differentiation in Osteoblastic Cells*

BMP-2-induced apoptosis was mediated by BMP-RIB in osteoblasts and occurred independently of B MP- 2-induced osteoblast differentiation, which provides additional insights into the dual mechanism of Bmp-2 action on osteoblow fate.

Recombinant human bone morphogenetic protein 2B stimulates PC12 cell differentiation: potentiation and binding to type IV collagen

Direct experiments demonstrated that radioiodinated BMP 2B bound to collagen type IV better than to either laminin or fibronectin, and suggest that these regulatory molecules alone and in conjunction with extracellular matrix components may play a role in both the development and repair of nervous tissue.

Identification of type I receptors for osteogenic protein-1 and bone morphogenetic protein-4.

Results suggest thatALK-3 and ALK-6 are type I receptors for OP-1 and BMP-4; in addition, ALk-2 is a type I receptor shared by activin and OP- 1, but not by B MP-4.

Cloning and characterization of a human type II receptor for bone morphogenetic proteins.

The cDNA cloning and characterization of a human type II receptor for BMPs (BMPR-II) is reported, which is distantly related to DAF-4, a BMP type II receptors from Caenorhabditis elegans.

Molecular cloning of rat bone morphogenetic protein (BMP) type IA receptor and its expression during ectopic bone formation induced by BMP.

A cDNA for the rat bone morphogenetic protein (BMP) type IA receptor (BMPR-IA) was isolated from a dental pulp cell cDNA library and reverse transcriptase-polymerase chain reaction analysis revealed that BMPR- IA mRNA was highly expressed in the BMP-induced bone forming tissues throughout the stages tested.

Distinct spatial and temporal expression patterns of two type I receptors for bone morphogenetic proteins during mouse embryogenesis.

The complementary DNA cloning of the mouse homolog of ALK-3 is reported, which is highly conserved between mouse and man, and the expression in sites of developing cartilage and bone supports the idea that ALK3 and -6 are receptors for BMPs in vivo.

The cartilage- and bone-inductive activity of the recombinant BMP-2A is histologically indistinguishable from that of bone extracts, and has therapeutic potential to promote de novo bone formation in humans.
