ANR New funding by ANR for IDEAL-3D

The REGOS team of the Inserm U1229-RMeS laboratory is pleased to announce the recent funding of the IDEAL-3D proposal as an ANR collaborative research project. IDEAL-3D will be coordinated by Sylvain Catros (BIOTIS, Bordeaux) with Alexandra Cloitre and Philippe Lesclous (RMeS), with Lise Chagot (BIOTIS, Bordeaux), with Makoto Miyara (CIMI, Paris) and Nicolas Courtois (ANTHOGYR, Sallanches). The aim of this project is to fabricate and evaluate an in vitro 3D model representative of the processes of osseointegration and soft tissue integration of dental implants, using Bioprinting techniques, in order to serve as a reliable and reproducible platform for research in implant dentistry.

ANR New funding by ANR for CREABONE

The REGOS team of the Inserm U1229-RMeS laboratory is pleased to announce the recent funding of the CREABONE proposal as an ANR collaborative research project. CREABONE will be coordinated by Federico Perche and Chantal Pichon (UPR 4301 CNRS, CBM, Orléans) with Pierre Weiss and Valérie Geoffroy (RMeS) and Delphine Logeart-Avramoglou (B3OA - CNRS UMR705, Inserm U1271). The CREABONE project proposes to deliver messenger RNA (mRNA) coding BMPs (Bone morphogenetic proteins) as an innovative alternative to protein therapy or gene therapy for bone tissue regeneration (mRNA therapeutics delivery). The overall objective of the project is to formulate mRNA-lipid vector-hydrogel composite matrices (CreaBone) allowing a safe, local and transient expression of BMP dimers by host progenitor cells and to validate their therapeutic efficacy for bone regeneration..

ANR New funding by ANR for IMAGIN

Scientists from RMeS (REGOS Team), based at the University of Angers are pleased to announce the recent funding of the IMAGIN proposal as an ANR collaborative research. This project is based on the recent work of the group of Prof C. Ruckebusch (University of Lille) on chemical unmixing of spectral images combined to sparse sampling approach developed in the group of Prof N. Dobigeon (University of Toulouse). A new approach of sparse sampling, based on machine learning in chemical imaging, will be developed by Prof. D. Rousseau (University of Angers). Scientists from RMeS,  will be involved in developing a model of bone pathology with alteration of the chemical signature of bone. If successful, this approach should pave the way for the investigation of bone material properties in situ without having access to bone biopsies but also in a rapid acquisition that could be translated to clinical practice.
