Current clinically used delivery methods for bone morphogenetic proteins (BMPs) are collagen based and require large concentrations that can lead to dangerous side effects. Fibrin hydrogels can serve as osteoinductive bone substitute materials in non-load bearing bone defects in combination with BMPs. Two strategies to even further optimize such a fibrin based system include employing more pote...
In Drosophila, the BMP binding protein Short gastrulation (Sog) both enhances and inhibits BMP activity in a spatially dependent manner, likely by facilitating transport of BMPs. In this report we examine the properties of a second Sog-like protein, Crossveinless 2 (Cv-2), and show that like Sog, it is a secreted BMP-binding protein that can either augment or inhibit BMP signaling. Unlike Sog h...
OBJECTIVE To determine if a dual-purpose bone graft can regenerate bone and reduce infection in highly contaminated bone critical size defects in rats. METHODS Biodegradable polyurethane (PUR) scaffolds were loaded with recombinant human bone morphogenetic protein-2 (BMP-2) and vancomycin (Vanc). The release kinetics of the BMP-2 were tuned to take advantage of its mechanism of action (ie, an...
Abstract High efficiency of hybrid implants based on calcium-magnesium silicate ceramic, diopside, as a carrier recombinant BMP-2 and xenogenic demineralized bone matrix (DBM) scaffold for tissue regeneration was demonstrated previously using the model critical size cranial defects in mice. In order to investigate possibility these growing autologous vivo bioreactor principle patient’s own body...
The effects of Bone morphogenetic protein 2 (BMP-2) on the angiogenesis of hepatocellular carcinoma have not yet been observed and its molecular mechanisms is not clear. We first constructed the recombinant lentivirus vectors expressing small hairpin RNA against BMP-2 gene (LV-SH-BMP2) and the recombinant lentivirus vectors over-expressing BMP-2 (overexpression-LV-BMP2), and then the two recomb...
Bone morphogenetic protein-2 (BMP-2) is considered a promising adjuvant for the treatment of skeletal non-union and spinal fusion. However, BMP-2 delivery in a conventional collagen scaffold necessitates a high dose to achieve an efficacious outcome. To lower its effective dose, we precomplexed BMP-2 with the glycosaminoglycans (GAGs) dermatan sulfate (DS) or heparin (HP), prior to loading it i...
Distal outgrowth and maturation of mesenchymalized endocardial cushions are critical morphogenetic events during post-EMT atrioventricular (AV) valvuloseptal morphogenesis. We explored the role of BMP-2 in the regulation of valvulogenic extracellular matrix (ECM) components, versican and hyaluronan (HA), and cell migration during post-EMT AV cushion distal outgrowth/expansion. We observed inten...
Aldosterone and angiotensin II (ANG II) contribute to the development and progression of renal damage. Here we investigated the effects of bone morphogenetic proteins (BMPs) on renal cell proliferation evoked by aldosterone and ANG II with mouse mesangial cells, which express mineralocorticoid receptors (MR), ANG II type 1 receptors, and BMP signaling molecules. Aldosterone and ANG II stimulate...
We investigated the action of 1alpha,25-dihydroxyvitamin D(3) [1alpha,25(OH)(2)D(3)], a novel Gemini vitamin D(3) analog Ro-438-3582 [1alpha,25-dihydroxy-20S-21(3-hydroxy-3-methyl-butyl)-23-yne-26,27-hexafluorocholecalciferol (Ro3582)], and a classic vitamin D(3) analog Ro-26-2198 [1alpha,25-dihydroxy-16,23(Z)-diene-26,27-hexafluoro-19-nor-cholecalciferol (Ro2198)] in modulating the transformin...
