Fibrodysplasia ossificans progressiva (FOP) is a rare, autosomal dominant disorder characterized by heterotopic ossification (HO) in muscles, ligaments and tendons. Flare-ups often precede formation of HO, resulting in immobilized joints. Recently, it has been shown that [18F]NaF PET/CT could identify early ossifying disease activity during flare-ups. HO may progress without signs of flare-up, but its underlying physiology is not understood. We wondered whether [18F]NaF PET/CT...

Background: Fibrodysplasia Ossificans Progressiva (FOP) is a progressive disease characterized by periods of heterotopic ossification, often in ligaments. The underlying mechanism is far from clear, partially due to limited access to patient-derived cell models. Periodontal ligament fibroblasts (PLF) from extracted teeth can potentially be used to study deviant bone remodelling processes in vitro since these cells are derived from actual ligaments. They further provid...
