Bone morphogenetic protein (BMP) is the only cytokine that induces heterotopic new bone. BMP has been classified as a subfamily of TGF superfamily. The most important and essential aspect for clinical application replenishment reinforcement bone defects fragile areas with However, it difficult to ascertain long term results. In this study, we examined osteogenic potential in mouse femoral fasci...

Background :
 The use of Bone Graft in the management Defect is a challenge world orthopedics. Recently, eggshell containing hydroxyapatite has become new hope an economical and efficient bone graft treatment defects. aim this systematic review was to explore available literature on clinical performance eggshells as grafts guided regeneration.
 Method Two databases (PubMed Cochrane) w...

62 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 1 Abstract The purpose of this study was to evaluate the repair process in the reconstruction of the anterior wall of the frontal sinus of monkeys with bovine bone matrix. Four adult Cebus apella monkeys underwent an ostectomy of the anterior wall of the frontal sinus. The frontal sinus mucosa and the nasofrontal duct were not manipu...

This study evaluated the morphological and chemical composition of the following bone substitutes: cancellous and cortical organic bovine bone with macro and microparticle size ranging from 1.0 to 2.0 mm and 0.25 to 1.0 mm, respectively; inorganic bovine bone with particle size ranging from 0.25 to 1.0 mm; hydroxyapatite with particle size ranging from 0.75 to 1.0 mm; and demineralized freeze-d...

A 25-kDa homodimeric protein was purified from demineralized bovine bone extract and identified as activin A. The bovine bone activin enhanced formation of ectopic bone in rat subcutis when implanted in combination with partially purified bovine bone morphogenetic protein (BMP-2, BMP-3) in collagen/ceramic carrier. The implants, removed at 14 days, contained markedly elevated levels of alkaline...

The pattern of mineralization was studied in the mandibular condyle of the young adult rat. Specimens were rendered anorganic in NaOC1 and examined in a scanning electron microscope. A mineralized cartilage front was found to persist on the articular aspect of the condyle. The surface is characterized by closely approximating chondrocyte lacunae enclosed to different degrees within the minerali...

PURPOSE An-organic bovine bone graft is a xenograft with the potential of bone formation. The aim of this study was to evaluate the bone density using cone beam computed tomography scans around functional endosseous implant in the region of both augmented maxillary sinus with the an-organic bovine bone graft and the alveolar bone over which the graft was placed to provide space for the implants...

OBJECTIVE This study evaluated in vitro differentiation of mesenchymal stromal cells isolated from bone marrow, in tenocytes after treatment with bovine tendon extract. METHODS Bovine tendons were used for preparation of the extract and were stored at -80 °C. Mesenchymal stromal cells from the bone marrow of three donors were used for cytotoxicity tests by means of MTT and cell differentiatio...
