Synovial fibroblast biology Dr Fraser Collins Versus Arthritis Career Development Fellow Contact details Email: fraser.collins@ed.ac.uk Research in a NutshellI am an investigator in the Rheumatology Research Group. Meet our Team and read about our research on our Team page. Rheumatology Research Group My research focuses on the molecular regulation of fibroblast-like synoviocytes (FLS), a specialised cell type in the synovial lining that is crucial for maintaining a healthy joint. Using preclinical models of cartilage injury, 3D organoid systems that replicate joint tissue structures and single-cell omics technologies, we aim to identify factors that control the differentiation and maintenance of adult FLS and understand how they become dysregulated following joint injury and arthritis.
