This book was released on 2005-09-01 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the latest updates on the major challenges of bridging large bone defects, where options range from autografts, “tissue engineered bone”, biomaterials (hydroxyapatite, polycaprolactone and third generation biomaterials) to prostheses. Emphasis has been made on bone tissue engineering, the current state-of-the-art in this field, problems encountered with cell culture technology, scaffolds and bone growth factors (including genomics) and the use of gene therapy for the application of bone growth factors. Attention has also been given to the use of bone autografts. It also covers the use of biomaterials and prostheses as other options for reconstruction. Clinical applications, in addition to the basic science, are also included throughout the discussions.

In the United States alone over 250,000 bone grafts were harvested annually. While autogenic bone grafting has always been associated with donor site morbidity, bone graft substitutes have been suggested as a solution. In this project, a bone graft substitute using human dental pulp cells (HDPCs) and peptide nanofibre hydrogel was being developed. HDPCs were isolated from extracted teeth. After culture and expansion, unsorted HDPCs were encapsulated into peptide nanofibre hydrogel. These cell-gel constructs were cultured for two weeks in ordinary culture medium and then for 2-3 more weeks in osteogenic lineage induction medium. The post-induced cell-gel derived constructs were transplanted into skin pouches or calvarial bone defects of nude mice. When transplanted subcutaneously, the cell-gel derived constructs were harvested at four to twelve weeks postoperatively (n=5). Tissue samples were processed for contact radiograph, histological examination and antibody staining. These constructs developed into vascularised, mineralised tissue pieces. Though bone marker proteins (osteopontin, osteocalcin and osteonectin) were detected in these tissue pieces, the histological structure of their tissue matrix did not resemble bone matrix. Later, it was accidentally noted that portions of constructs touching the bone defect margin, would form bone through direct matrix transformation. This indicated that the current cell-gel model was potentially the first study model of tissue engineering bone by simulating intramembranous ossification. In the bone defect trial, obviously mineralized cell-gel derived constructs of matching shape and size were selected to patch the 3mm calvarial bone defects (n=5). Bone defect specimens were harvested at two weeks post-operation. The development of radio-opaque structures within the bone defects were evaluated in virtual 3-dimensional models constructed with data collected by microtomographic scanning. The bone nature of these radio-opaque structure were validated histologically (by staining with Hematoxylin and Eosin, Periodic acid-Schiff stain and Picrosirius red) and immunologically (with antibody against human collagen-I, osteonectin and parathyroid hormone receptor). The radio-opaque structures developed into the bone defect were evaluated positive for bone. And significantly more bone regeneration was observed in the test group (n=4) than in the control (n=2). The mean area percentages of regeneration were 46.3% and 0% respectively (pWhile the majority of studies in bone tissue engineering have worked with bone marrow stromal cells and scaffolds of synthetic polymer or calcium based materials, this is the first successful attempt of using HDPCs and peptide nanofibre hydrogel to engineer bone (in a nude mice mode). And the potential of these cell-gel derived constructs to promote bone regeneration was demonstrated. But this was the result from a single experiment of small sample size in one animal model only. It needs to be fortified by further experiments with larger population size and in other animal models. To increase clinical usefulness, the construct will need to be scaled up to centimetre size level. This will necessitate a change of its configuration from bead into meshw
Download or read book Ceramic Materials Mimicking Normal Bone Surface Microstructure and Chemistry Modulate Osteoblast Response written by Brandy Rogers Adams and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone consists of collagen/hydroxyapatite (HA) composites in which poorly crystalline carbonated calcium phosphate is intercalated within the fibrillar structure. Normal bone mineral is a carbonated-apatite, but there are limited data on the effect of mineral containing carbonate on cell response. Although the exact biological role of silicate in bone formation is unclear, silicate has been identified at trace levels in immature bone and is believed to play a metabolic role in new bone formation. To mimic the inorganic and organic composition of bone we have developed a variety of bone graft substitutes. In the present body of research, we characterized the surface composition of human cortical and trabecular bone. When then characterized the surface compositions of the following potential bone substitutes: carbonated hydroxyapatite (CO32-HA), silicated hydroxyapatite (Si-HA), and collagen sponges mineralized with calcium phosphate using the polymer-induced liquid-precursor (PILP) process. In the latter substitutes, the PILP process leads to type I collagen fibrils infiltrated with an amorphous mineral precursor upon which crystallization leads to intrafibrillar HA closely mimicking physiological bone mineral. We then determined the osteoblast-like cell response to each bone substitute to characterize the substrate's effect on osteoblast differentiation. The observations collectively indicate that cells are sensitive to the formatting of the mineral phase of a bone substitute and that this format can be altered to modulate cell behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Hydroxyapatite in the form of hydroxycarbonate apatite is the principal mineral component of bone tissue in mammals. In Bioceramics, it is classed as a bioactive material, which means bone tissue grows directly on it when placed in apposition without intervening fibrous tissue. Hydroxyapatite is hence commonly used as bone grafts, fillers and as coatings for metal implants.
