Team presentation

The "Biomaterials and Inflammation in Bone Site" laboratory combines biological and clinical approaches to understand the bone physiopathology orphan diseases (cystic fibrosis, fibrous dysplasia) and to develop innovative osteoinductive and osteoregenerative biomaterials for bone filling, particularly in inflammatory and/or septic sites.

Research topics

Our multidisciplinary program combines chemistry, cell biology, immunology, microbiology, numerical modeling, animal models and transfer to clinical applications and technological innovations for bone regenerative medicine. It is based on the following themes:

- Bone physiopathology in rare diseases (cystic fibrosis, fibrous dysplasia ...),
- Conceptualization and validation of innovative scaffolds,
- Regenerative medicine and stem cells,
- Biological processes influencing the regenerative capacities of biomatrices and cellular immunomodulation (inflammation, infection, tissue neoformation ...),
- Cold plasma sterilization process of pre-conditioned materials.

Know-how

- Human primary bone cell cultures in vitro and ex vivo, as well as human and murine cell lines,
- Culture of adult and fetal stem cells,
- Planktonic bacterial cultures or biofilms and validation of antimicrobial activities,
- Models of co-culture, cell / biomaterial interaction, bacteria / cells, bacteria / cells / biomatrices
- Elaboration of hydrogels, biomaterials based on natural polymers (collagen, chitosan, hyaluronic acid ..),
- Migration / cell invasion models,
- Histological, immunohistochemical and immunological techniques,
- Cell and tissue imaging,
- In vivo experimental validation: experimental animal models (mouse and rat).
