Group description    
We like a mixed population of students and scientists i.e. both those with a medical background and those with a scientific background, thereby building the bridge between clinic and basic research from both ends.
Introduction to research area
Most of our research is driven by the identification of the biological mechanism of bone loss, since this is the primary cause of fractures, pain and disabilities. Bone loss is due to dysregulation of bone remodeling, a process consisting in removal of “old bone” by osteoclasts and formation of “new bone” by osteoblasts. Traditional research is therefore focusing on bone resorption and formation. In contrast, Clinical Cell Biology is focusing on the remodeling step reversing resorption to formation and therefore investigates how bone sites that underwent resorption are prepared for bone formation.

Hallmarks of our research
    •Every effort to make observations on human material
    •Attention for heterogeneity amongst individuals (rather than for averages)
    •From bedside to lab bench: in vivo observations triggering the development of in vitro models
    •Attention to intratissular cell organization (not only to genes) to understand function: “functional (rather than descriptive) histology”
    •Integrative  (rather than analytical)
    •Ranges from clinical trials to mechanistic studies

Helping the patient by providing specialized research expertise, which is usually not present in the clinic
