Tissue engineering (te) is a relatively new and emerging interdisciplinary field that applies the knowledge of bioengineering (the life sciences) and the clinical sciences towards solving the critical medical problems of tissue loss and organ failure. Associate professor of bioengineering thesis co-supervisor william o hancock associate professor of bioengineering a sample application of finite element analyses to studies of skeletal tissue engineering is that of bone remodeling in the morphogenesis of skeletal tissue, bone undergoes changes of mechanical properties and changes of. Bone is one of the most transplanted tissues in the world and the current clinical strategies are unable to meet the growing demand for bone grafts therefore, bone tissue engineering (bte) has become one of the potential alternatives to produce highly cellularized and mineralized bone grafts to meet the growing demand in clinics. In vivo bone tissue engineering is an emerging field of regenerative medicine for bone defects, which differs from classical tissue engineering in vivo bone tissue engineering uses the body as a “bioreactor” to construct bone graft with intrinsic osteoinductive biomaterials in the non-osseous or osseous sites. Currently, one of the most promising strategies in bone tissue engineering focuses on the development of biomimetic scaffolds ceramic-based scaffolds with favorable osteogenic ability and mechanical properties are promising candidates for bone repair.
