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...
Pluripotent mesenchymal stem cells (MSCs) are bone marrow stromal progenitor cells that can differentiate into osteogenic, chondrogenic, adipogenic, and myogenic lineages. Several signaling pathways have been shown to regulate the lineage commitment and terminal differentiation of MSCs. Here, we conducted a comprehensive analysis of the 14 types of bone morphogenetic protein (BMPs) for their ab...
The authors compared the results of treating nonunion with either bone morphogenetic protein (BMP)-7 or BMP-2. Between 2001 and 2009, 214 limb segments were treated for nonunion with either BMP-7 or BMP-2 at the authors' institution. Sixty-three subjects received 76 units of BMP-7. Radiographic healing occurred in 70% of limb segments at an average of 30 weeks after surgery, and 75% of limb seg...
STUDY DESIGN Quantitative gene expression analysis and immunohistochemistry were used to investigate the temporal and spatial expression of bone morphogenic proteins (BMPs) and BMP antagonists in a posterolateral spine fusion model in rabbits. OBJECTIVE To identify the expression pattern of BMPs and BMP antagonists and to determine the molecular and histologic changes of the graft and surroun...
Bone morphogenetic protein-2 (BMP-2), a member of the transforming growth factor-beta (TGF-beta) family, regulates osteoblast differentiation and bone formation. Here we show a novel function of BMP-2 in human osteoblasts and identify a signaling pathway involved in this function. BMP-2 promotes apoptosis in primary human calvaria osteoblasts and in immortalized human neonatal calvaria osteobla...
BACKGROUND Phosphatase homologue of tensin (PTEN) is the most commonly mutated gene in prostate cancer. Bone morphogenetic proteins (BMPs) are known to promote differentiation and inhibit proliferation. Previously published reports from other organ systems led us to investigate a mechanistic relationship between PTEN and BMP signaling in prostate epithelial cells. METHODS We analyzed growth r...
TGF-beta is a therapeutic target for renal fibrosis. Scientists have long sought ways to antagonize TGF-beta to ameliorate diabetic nephropathy. Bone morphogenetic protein (BMP-2) is a member of the TGF-beta superfamily and is highly regulated in the kidney. Thus, the role of BMP-2 was investigated in NRK-49F cells (rat fibroblasts). We showed that TGF-beta1 induces an increase in fibronectin. ...
Rationale: The importance for Bmp signaling during embryonic stem cell differentiation into myocardial cells has been recognized. The question when and where Bmp signaling in vivo regulates myocardial differentiation has remained largely unanswered. Objective: To identify when and where Bmp signaling regulates cardiogenic differentiation. Methods and Results: Here we have observed that in zebra...
Yan, H. 2016. New insights into principles of scaffolds design for bone application. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1459. 87 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9767-5. This thesis presents deeper insights into bone applicable biomaterials’ design. Poor affinity of BMP-2 towards scaffolds required supr...
Angiogenesis is considered essential for proper bone regeneration. The purpose of this investigation was to determine if a combined therapy of bone morphogenetic protein-2 (BMP-2) and cartilage oligomeric matrix protein angiopoietin-1 (COMP-Ang1) can potentiate the therapeutic effect of BMP-2 in a rat model of ischemic necrosis of the femoral head (INFH). INFH was surgically induced in the femo...
