Summary
Hip replacements often fail due to the loss of adjacent bone. Metal or polyethylene particles are produced as the prosthesis bearing surface wears but how do these particles lead to bone loss? Our work suggests involvement of osteocytes within the bone mineral, which are increasingly understood to drive bone physiology and pathology. We will explore the role of the osteocytes by examining their response to particles, which may identify a new target to prevent particle-induced bone loss.
Mechanisms Of Premature Cranial Fusion: Role Of Retinol Binding Protein 4 In Osteogenesis And Suture Fusion

Summary
Craniosynostosis is a condition where the skull bones fuse prematurely, affecting skull shape, vision and cognition. It occurs in 1 in 2,500 births. The only treatment is surgery, which is life-threatening, costly and may need to be repeated. By studying how fusion happens in this project we may be able to devise therapies to minimize the risks and need for re-operation. Here, we hope to show that modification of a single substance in the skull of mouse models can prevent premature bone fusion.

Summary
Lymphatic vessels are essential to maintain fluid balance in most tissues of the human body. Further the lymphatic vasculature plays a central role during cancer and contributes to tumour metastasis. Despite this integral function in health and disease little is known about the molecular programs that coordinate gene expression to build a functional vasculature. This research project will address this gap in our knowledge and will open up new therapeutic avenues for lymphatic vascular disorders
Regulation Of Key Pathways Causing Peri-implant Bone Loss.

Summary
The failure of bone prostheses is becoming a major health problem in our aging population. Despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is now apparent that most implants fail due to bone loss around them which leads to loosening. This project aims to obtain a better understanding of the causes of implant failure and find ways to extend the life of these implants .
