Age related musculoskeletal diseases increase the risk of bone fractures and, as the population ages, their treatment will cost the NHS £6bn by 2036. Osteoporosis alone affects an estimated 3 million people in the UK; with 300,000 bone fractures treated by the NHS every year; these have a great impact on the patients’ quality of life and are associated to high mortality. Existing “gold standard” treatment protocols (i.e. autografts or allografts) are limited by inadequate availability of donor’s tissue, donor site morbidity, risk of infection, etc. Alternative materials are used in the clinic but they are also affected by serious drawbacks such as limited osteoinductivity and inadequate mechanical behaviour (i.e. stiffness and brittleness); hence, novel strategies must be developed to improve current treatments. The development of novel materials able to induce controlled bone formation, and presenting an adequate resorption kinetic, is considered the most promising route. In the development of these biomaterials, it is key to understand the joint role of biological environment and mechanical stimuli (aka ‘mechanoregulation’) typical of physiological conditions; and their dependence on the type of material used. To date, the preferred way to study this aspect is performing studies in animals; these can provide a real physiological environment to assess biomaterials efficacy in bone tissue regeneration. Unfortunately, this strategy employs countless animals with high cost and implicit ethical issues.
The aim of the proposed research is to develop the first in vitro protocol for the study of the role of osteoregenerative biomaterials in bone regeneration. The relationship between the mechanical characteristics of the employed biomaterials and their ability to produce new quality bone in a biological environment will be investigated. The research will provide a better understanding of the outcome of bone formation when simulated physiological loading is applied, resulting in the development of better bone repair materials. In addition, correlative imaging combining confocal microscopy, x-ray microscopy and mechanical testing will ensure in-depth knowledge of the entire transition from cell activity to regenerated tissue. The project will increase knowledge on bone formation related to biomaterial design and mechanical stimulation, providing the first in vitro platform aiming to substitute animal studies in the next future and representing a breakthrough methodological tool for the development of new treatments.
You’ll need a good first degree from an internationally recognised university (depending upon chosen course, minimum second class or equivalent) or a Master’s degree in an appropriate subject. Exceptionally, equivalent professional experience and/or qualifications will be considered. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.
