PURPOSE To evaluate in vitro ability the of three different biomaterials - purified hydroxyapatite, demineralized bone matrix and castor oil-based polyurethane - as biocompatible 3D scaffolds for canine bone marrow mesenchymal stem cell (MSC) intending bone tissue engineering. METHODS MSCs were isolated from canine bone marrow, characterized and cultivated for seven days with the biomaterials...
Adipose-derived mesenchymal stem cells (ADMSCs) are inducible to an osteogenic phenotype by the bone morphogenetic proteins (BMPs). This facilitates the generation of implants for bone tissue regeneration. This study evaluated the in vitro osteogenic differentiation of ADMSCs transduced individually and in combination with adenoviral vectors expressing BMP2 and BMP7. Moreover, the effectiveness...
the gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kgy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. this work carried out using an experimental method in an animal model. in this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kgy...
Background and Aims: The present study was designed for evaluation of bovine demineralized bone matrix (DBM) in healing process of bone defects and comparison of bovine DBM (xenograft) and human DBM (allograft) which is used clinically. Materials and Methods: Seven male white New Zealand rabbits were used in this study. The incision was made directly over the midsagital suture of the parietal b...
An investigation was conducted to test the feasibility of demineralized bone matrix and cancellous bone chips in a reverse-phase medium carrier (DynaBlast) in concert with an extracellular matrix membrane (DynaMatrix) to provide hard and soft tissue regeneration for the purpose of a ridge preservation procedure. Nine patients requiring extraction of 30 maxillary teeth were grafted with DynaBlas...
background: it has been stated that the bone allografts from different tissue banks may lead to various amount of bone induction, so the aim of this study was to evaluate bone regeneration of three demineralized allografts both histologically and histomorphometrically in rabbits calvaria bone defects. materials and methods: in this double-blind randomized experimental animal study, 32 critical ...
PURPOSE This study compared the dentin collagen cross-linking potential of carbodiimide (EDC) prepared in three most commonly used solvents in dental adhesive systems: water, ethanol, and acetone. MATERIALS AND METHODS Thirty-eight extracted caries-free human permanent molars were used in this study. Demineralized dentin beams were prepared and cross linked by 0.3 M EDC in water, acetone, or ...
Tissue engineering has been used to enhance the utility of biomaterials for clinical bone repair by the incorporation of an osteogenic cell source into a scaffold followed by the in vitro promotion of osteogenic differentiation before host implantation. In this study, three-dimensional, partially demineralized bone scaffolds were investigated for their ability to support osteogenic differentiat...
