A large number of bone substitute materials are available; for which some authors claim osteoconductivity and some osteoinductivity. In order to rank these materials an in vivo analysis was carried out. These materials were chosen based on their availability and claimed mode of action.

Abstract:
Background: Bone-grafting materials are required in orthopaedic surgery to treat bone defects. Bone formation assessment is required for the development of new strategies and approaches and for quality assurance and quality control of currently available materials. Approaches to the assessment of bone formation are yet to be systematically established, quantified and standardized. Aims: the overall aim of this study was to establish a set of comprehensive quantitative approaches for the assessment of bone formation and to evaluate the role of osteoblastic cells, growth factors, and scaffolds

Abstract:
Osteoblast-derived vascular endothelial growth factor (VEGF) is important for bone development and postnatal bone homeostasis. Several studies have demonstrated that VEGF affects bone repair and regeneration; however, the cellular mechanisms by which it works are not fully understood. In this study, we investigated the functions of osteoblast-derived VEGF in healing of a cortical bone defect. In addition, how VEGF signaling modulates BMP2 functions during bone healing was also examined. To define the roles of osteoblast-derived VEGF in bone repair, a mouse tibial monocortical defect model was

Skeletal fragility is characterized by low bone mass, negative changes in bone microarchitecture, and compromised tissue matrix properties, including accumulation of microdamage. Microdamage accumulates in vivo from daily physiological loading and is targeted for repair through a normal remodeling process, thus preventing microcrack growth and potential fracture. However, impaired remodeling is associated with aging and osteoporosis, resulting in an increased accumulation of microdamage which contributes to reduced bone mechanical properties.

The most common clinical treatments for large bone deficiencies resulting from trauma, disease or infection are autograft, allograft or bone graft substitutes (BGS). However, these treatments still have limitations for clinical applications. Thus, this project aims to fabricate an optimal scaffold design for enhanced bone formation. Human bone is not solely hydroxyapatite (HA) but consists of multi-ionic substitutions in the HA lattice.

Abstract:
During fracture healing, many complex and cryptic interactions occur between cells and bio-chemical molecules to bring about repair of damaged bone. In this thesis two mathematical models were developed, concerning the cellular differentiation of osteoblasts (bone forming cells) and the mineralisation of new bone tissue, allowing new insights into these processes. These models were mathematically analysed and simulated numerically, yielding results consistent with experimental data and highlighting the underlying pattern formation structure in these aspects of fracture healing.

Emerging evidence indicates that the dysregulation of protein ubiquitination plays a crucial role in aging-associated diseases.

However, whether the dysregulation of Smad1/5 ubiquitination and disrupted BMP signaling pathway are responsible for the age-related bone formation reduction is still underexplored.

Abstract:
Distraction Osteogenesis (DO) is a technique for bone lengthening and filling of bone defects following trauma, infection or resection of tumors. DO consists of an osteotomy of the bone to be lengthened, followed by controlled distraction of the bone segments with an external fixator until the desired lengthening is obtained (distraction phase). This is followed by the consolidation phase, during which the external fixator is kept in place until the newly formed bone in the distracted zone consolidates. This phase is long and may cause numerous problems. Ongoing research aims at finding a meth

These two cytokines bind to the osteoclast precursor cells, activating various down stream signalling pathways, inducing genes required for differentiation and for activation of osteoclasts.
