Professor Rachel O'Brien-Waddington
Director of Staff Wellbeing and Development, Professor of Oral Biochemistry
Overview
Rachel Waddington is a Professor in Oral Biochemistry. With more than 30 years' experience, my research has had a long-standing focus for understanding the role of the extracellular matrix environment in the regulation the biology of bone and dentine repair; research that aims to be translational for provoking clinical benefit.
Matrix components and extracellular vesicles produced by mesenchymal stem / progenitor cells contain and regulate the release of a rich cocktail of growth factors, that are collectively important in directing effective and efficient cell signalling during cell differentiation. Recently my research has investigated:
- how the extracellular matrix environment is altered during systemic conditions such as chronic type 2 diabetes mellitus, leading to inefficient cell signalling that compromises the healing process and exacerbates periodontal tissue destruction;
- how the extracellular matrix environment is altered by blue light therapies and the role of reactive oxygen species in this process.
- investigating tissue and cell derived matrix products and extracellular vesicles for restoring the signalling environment and potentially reverse delayed bone healing often encountered with these systemic conditions;
- the influence of modifying titanium implant surfaces on cellular activity that is beneficial for promoting bone healing and hence allows for quicker and more efficient integration of medical implants.

Research
The clinical management of bone fractures and implant placement, including revision / replacement is orientated towards obtaining bone healing in the shortest time frame, with the best possible functional recovery, and with the least complications arising; features that remain a challenge for patients with osteoporosis or chronic diabetes. Against this clinical challenge my research has developed a focussed interest towards understanding and exploiting the role of extracellular matrix in directing bone and dentine repair. Below is a summary of current research projects.
- Alterations to extracellular matrix proteins associated with type 2 diabetes mellitus
Within these systemic conditions, the biological activity of mesenchymal stem cells is reported to be impaired leading to delayed bone healing. Within this field of research we have been investigating how a hyperglycaemic environment can lead to changes in the levels of extracellular proteins decorin, biglycan, transforming growth factor ß and osteopontin - all of which have the potential to hinder the synthesis of a fully mineralised tissue. Additional studies have investigated how bacterial virulence factors can exacerbate these changes with detrimental consequence for progression of periodontal disease and osteomyelitis in these patients.
- Cell and tissue derived matrix-based therapies for restoring signalling environment associated with delayed bone healing
The extracellular matrix is a rich source of growth factors, integrated into the extracellular matrix that regulates their activity. Our research has investigated the potential of demineralized dentine matrix as a store of growth factors capable of promoting bone repair processes. In addition, our research is currently investigating the potential of extracellular vesicles, secreted from dentally derived mesenchymal stem cells, and their role as carriers of a biologically active cargo capable of enhancing the differentiation of bone marrow stromal cells into bone synthesizing osteoblasts.
- Influence of modified titanium surfaces on bone repair processes
Through detailed studies involving a series of standardised cell- and tissue-based assays, we have investigated how defined and subtle surface modifications to titanium implant biomaterials can influence osteoblast differentiation. These studies additionally study cellular activity supporting angiogenesis and appropriate macrophage function, both of which are recognised as pre-requisites for successful bone healing.
