Bone morphogenetic proteins 9 & 10 in pulmonary arterial hypertension
… Mutations in BMPR2, which encodes the type-II bone morphogenic protein (BMP) receptor BMPR-II, explain the majority of heritable PAH. BMPR-II forms a signalling complex, with ALK1 and endoglin, specific to endothelial cells which maintains vascular quiescence. BMP9 and BMP10 are the high …

Apatite-polymer composites for the controlled delivery of bone morphogenetic proteins
Current treatment of bone defects due to trauma, cancer, or degenerative spine diseases involves the implantation of a bone graft. Autografts, which are harvested from the patient's own body, are associated with problems of limited availability and surgical morbidity. The use of allografts obtained …

Bone morphogenetic proteins (BMPs): new modulators of the follicle stimulating hormone (FSH) synthesis and release
… Other molecules of the TGF -13 superfamily, the Bone Morphogenetic Proteins (BMPs) have recently been involved for their action in reproduction at ovary level. Whether BMPs act at pituitary level and participate with other factors to regulate FSH production in females is not elucidated. In order …

The role of bone morphogenetic protein signalling in the control of skin repair after wounding. Cellular and molecular mechanisms of cutaneous wound healing mediated by bone morphogenetic proteins and their antagonist Noggin.
Bone morphogenetic proteins (BMPs) and their receptors (BMPRs) coordinate tissue development and postnatal remodelling by regulating proliferation, differentiation and apoptosis. However, their role in wound healing remains unclear. To study this, transgenic mice overexpressing Smad1 (K14-caSmad1) …

Role of oocyte-secreted factors in prevention of cumulus cell apoptosis and enhancement of oocyte developmental competence.
… means the nature of the paracrine network of bone morphogenetic proteins (BMPs) and their binding proteins involved in the regulation of cumulus cell apoptosis. OSFs, in particular BMP- 15 and BMP-6, but not growth differentiation factor 9 (GDF-9), reduced apoptosis of cumulus cells by …

Roles of Heparan sulfate in mesendoderm differentiation of human embryonic stem cells
… (HS)-binding growth factors, such as Wnt, bone morphogenetic proteins (BMP), and fibroblast growth factor (FGF), critically regulate cell fate decisions of ES cells. Here, we showed that HS-deficient derived from hESCs have impaired ability to differentiate into Brachyury-positive …

Probing early human embryonic development to characterize BMP signaling stimulators
Bone morphogenetic proteins (BMPs) sind sowohl in der Embryonalentwicklung als auch im adulten Organismus von entscheidender Bedeutung. Da ein fehlregulierter Signalweg mit zahlreichen chronischen und schwerwiegenden Krankheiten assoziiert ist, stellt dessen Modulierung einen vielversprechenden …

Retrospektive Studie über die Ergebnisse nach Implantation von autolysiertem, Antigen-extrahiertem, allogenem Knochen
Im Rahmen der von der Datenbank bone97 erfassten Zeitraums dieser Studie wurde an der Klinik und Poliklinik für Mund-, Kiefer-, Gesichtschirurgie der Universität Würzburg zwischen März 1990 und März 2002 in 1073 Fällen bei 794 Patienten (421 männlich und 373 weiblich) autolysierter, Antigen …

THE ROLE OF BMP SIGNALING AND ENDOGLIN IN REGULATION OF HEMATOPOIESIS
… the role of two important regulatory candidates, Bone Morphogenetic Proteins (BMP) and Endoglin in adult hematopoiesis. Several publications have described the importance of BMP signaling in specification of hematopoietic tissue in developing embryos. In Article I and II, we investigate the full …

Composite gelatin delivery system for bone regeneration
… to produce a gelatin scaffold for the release of bone morphogenetic proteins (BMPs) from composite particles. This delivery system, designed to regenerate bone, holds much promise as an alternative to bone grafts. The chemical properties of gelatin were examined through zeta potential …

The Role of Bone Morphogenetic Protein (BMP) Signalling in Lung Cancer and Lung Regeneration
Bone morphogenetic proteins (BMPs) are members of the transforming growth factor beta (TGFβ) super-family of signalling molecules. BMPs play crucial roles in developing and adult tissues during processes including proliferation, differentiation, apoptosis and epithelial-mesenchymal transition …

Body Size Regulation via BMP Signaling in <i>Caenorhabditis elegans</i>
… size. In Caenorhabditis elegans, a homolog of Bone Morphogenetic Proteins (BMP) is a major regulator of body size; functional loss of DBL-1 leads to a small body size. Due to a drastic change in body size in dbl-1 mutants, we have the advantage of studying body size as a monogenic trait and we …

Spatio-temporal investigation and quantitative analysis of the BMP signaling pathway
Bone Morphogenetic Proteins (BMPs) are key regulators for a lot of diverse cellular processes. During embryonic development these proteins act as morphogens and play a crucial role particularly in organogenesis. BMPs have a direct impact on distinct cellular fates by means of …

Expression und Isolierung des BMP-bindenden Proteins Ep45
Die BMPs (Bone morphogenetic proteins) sind Zytokine, die in fast allen Tieren exprimiert werden und zur TGF-β Superfamilie gehören. Sie spielen eine wichtige Rolle in der Knochenentwicklung, unter anderem auf Grund ihrer Fähigkeit, die Neubildung von Knochen auszulösen. Eine weitere Aufgabe der …

The Quantitative Assessment of Osteoinductivity of Human Demineralized Bone Matrix and cDNA Array Analysis of Osteogenic Differentiation in Human Periosteal Cells
<p>Demineralized bone matrix (DBM) has been extensively utilized in orthopeadic, periodontal, and maxillofacial applications. DBM comprises bone morphogenetic proteins (BMPs) that are essential regulators for endochondral bone formation. The current study was undertaken to establish the …

BMP Signaling through BMPR1A is Required for Establishment of Pancreatic Laterality
… signals for pancreatic development. Various bone morphogenetic proteins (Bmps) and Bmp receptors (Bmprs) are expressed in the pancreas and in the tissues that flank the pancreatic bud during pancreatic development. Bmp7, BmpR1a, and BmpRII are expressed in the pancreatic endoderm during …

Enhancing bone healing through concurrent anabolic- and anti-catabolic pharmacological treatment
… but some evolve into nonunions. Autologous bone graft is the gold standard for stimulating healing. However, donor site morbidity, and limited graft supply make alternatives interesting. Bone Morphogenetic Proteins, BMPs, are growth factors involved in bone signaling. They are available in …

Analysis of the Function of Megf7 During Development
Lrp4/Megf7, a member of the low-density lipoprotein receptor gene family, is a major regulator of tissue patterning during embryonic development. Prior to this work, the function Megf7 had largely been unknown. Eight distinct mutations in Megf7 were introduced into mice in order to facilitate a …
