BACKGROUND CONTEXT: Bone morphogenetic protein (BMP)-2/7 heterodimer is a stronger inducer of bone regeneration than individual homodimers. However, clinical application of its potent bone induction ability may be hampered if its use is accompanied by excessive inflammatory reactions. PURPOSE: We sought to quantitatively evaluate bone induction and inflammatory reactions by BMP heterodimer and corresponding BMP homodimers using ultra-high resolution magnetic resonance imaging (MRI) and micro-computed tomography...

Bone morphogenetic protein-2 (BMP-2) is one of the most frequently used osteogenic factors for osteogenesis. Macrophages, acting as both immune cells and osteoclast precursors, have an indispensable functional input during multiple stages of bone healing. This study aims to investigate the immunoregulatory role of BMP-2 on macrophages and the subsequent effects on osteogenesis. In the subcutaneous implantation study, gelatin sponge incorporated with 20 μg/mL BMP-2 rendered significantly enhanced macrophage infiltration compared to the gelatin sponge control...

PURPOSE: This study evaluates the synergistic effect of serial application of bone morphogenetic protein 2 (BMP2) and fibroblast growth factor 2 (FGF2) on both new bone formation and periodontal tissue regeneration using 1-wall intrabony defect in mongrel dogs. MATERIALS AND METHODS: One-wall defects were created at the mesial aspect of the mandibular first molars of 6 male mongrel dogs. Each mandibular defect received 1 of the 2 experimental treatments randomly (BMP2 or BMP2 + FGF2), and it was allowed to heal for either 4 or 8 weeks postoperatively...

Signal transduction of the conserved transforming growth factor-β (TGFβ) family signaling pathway functions through two distinct serine/threonine transmembrane receptors, the type I and type II receptors. Endocytosis orchestrates the assembly of signaling complexes by coordinating the entry of receptors with their downstream signaling mediators. Recently, we showed that the C. elegans type I bone morphogenetic protein (BMP) receptor SMA-6, part of the TGFβ family, is recycled through the retromer complex while the type II receptor, DAF-4 is recycled in a retromer-independent, ARF-6 dependent manner...

Melanoma inhibitory activity (MIA) affects the differentiation to hyaline cartilage and can inhibit the osteogenic potential of bone morphogenetic protein (BMP)-2 in mesenchymal stem cells (MSC). The aim of this study was to investigate if MIA also inhibits the osteogenic potential of BMP-2 in human articular chondrocytes during redifferentiation, which may lead to a higher grade of differentiation without calcification. HAC of four female patients (mean age: 73.75 ±6.98) were seeded into 3D culture for 28 days; after adding the recombinant proteins, four groups were formed (Control, BMP-2, MIA, BMP-2+MIA)...

OBJECTIVE: Similar to cancer, pulmonary arterial hypertension (PAH) is characterized by vascular remodeling, which leads to obliteration of the small pulmonary arteriole, with marked proliferation of pulmonary artery smooth muscle cells (PASMC) and/or endothelial cells dysfunction. Aberrant expression of tumor suppressor genes is closely associated with susceptibility to PAH. We hypothesized that α-solanine, a glycoalkaloid found in members of the nightshade family known to have antitumor activity in different cancers, reverses experimental PAH by activating the tumor suppressor-axis inhibition protein 2 (AXIN2)...

BACKGROUND: Human dermal-derived fibroblast cells (hDDFCs) are multipotent. Bone morphogenetic proteins (BMPs) are a group of cytokines that promote different developmental processes, including the formation of bone. BMPs can promote hDDFC osteogenesis, but the role of BMP7 in hDDFC osteogenesis in vitro and bone formation in vivo has not been investigated in depth. MATERIALS AND METHODS: HDDFCs were stably transfected with a human BMP7 recombinant adenovirus and osteogenic differentiation was examined by alkaline phosphatase staining and calcium accumulation...

In our quest to standardize our formula for a clinical trial, transforming growth factor-beta3 (TGF-β3) alone and in combination with bone morphogenetic protein-6 (BMP-6) were evaluated for their effectiveness in cartilage differentiation. Bone Marrow Stem Cells (BMSCs) and Adipose Derived Stem Cells (ADSCs) were induced to chondrogenic lineage using two different media. Native chondrocytes served as positive control. ADSCs and BMSCs proved multipotency by tri-lineage differentiations. ADSC has significantly higher growth kinetics compare to Chondrocyte only p ≤ 0...

BACKGROUND CONTEXT: Biodegradable calcium phosphate cement (CPC) represents a promising option for the surgical treatment of osteoporotic vertebral fractures. Due to augmented local bone catabolism, however, additional targeted delivery of bone morphogenetic proteins with the CPC may be needed to promote rapid and complete bone regeneration. PURPOSE: In the present study, an injectable, poly (l-lactide-co-glycolide) acid (PLGA)-fiber reinforced, brushite-forming cement (CPC) containing the bone morphogenetic protein GDF5 was tested in a sheep lumbar osteopenia model...

BACKGROUND: Recent studies indicate that recombinant human bone morphogenetic protein (rhBMP-2) in a demineralized bone matrix scaffold (MS) is a comparable alternative to iliac bone autograft in the setting of secondary alveolar cleft repair. Post-reconstruction occlusal radiographs demonstrate improved bone stock when rhBMP-2/MS is used, but lack the capacity to evaluate bone growth in three dimensions. This study uses cone beam computed tomography (CBCT) to provide the first clinical evaluation of volumetric and density comparisons between these two treatment modalities...

The transforming growth factor-β (TGF-β) network of ligands and intracellular signaling proteins is a subject of intense interest within the field of skeletal muscle biology. To define the relative contribution of endogenous TGF-β proteins to the negative regulation of muscle mass via their activation of the Smad2/3 signaling axis, we used local injection of adeno-associated viral vectors (AAVs) encoding ligand-specific antagonists into the tibialis anterior (TA) muscles of C57BL/6 mice. Eight weeks after AAV injection, inhibition of activin A and activin B signaling produced moderate (∼20%), but significant, increases in TA mass, indicating that endogenous activins repress muscle growth...

Bone morphogenetic protein-4 (BMP-4) inhibits luteinization of granulosa cells during in vitro growth (IVG) culture of bovine oocytes; however, oocytes derived from a 12 day IVG were less competent for development than in vivo-grown oocytes. We herein investigated whether an extended IVG culture with BMP-4 improves oocyte growth and development to blastocysts after in vitro fertilization. Oocyte-granulosa cell complexes (OGCs) were cultured for 14 or 16 days with BMP-4 (10 ng/mL), while a 12 day culture with BMP-4 served as the in vitro control...
