New funding of ANR 2019

The STEP team of the INSERM U1229-RMeS laboratory is pleased to announce the recent funding of the EXCELLDISC proposal as an ANR collaborative research project. EXCELLDISC will be coordinated by Catherine Le Visage (INSERM U1229, RMeS) and will be carried out in collaboration with Florence Gazeau (MSC CNRS 7087) and Grégory Lavieu (U932, Institut Curie). EXCELLDISC will investigate whether MSC-derived extracellular vesicles (EVs) could contribute to slow down, stop or reverse intervertebral disc degeneration. .

New funding of ANR JCJC 2019

The REGOS team of the INSERM U1229-RMeS laboratory is pleased to announce the success of the BILIPOX project in ANR JCJC 2019. The laboratory will receive a grant of 305k€ for 3 years to hire dedicated staff (Engineer and technician). The BILIPOX project will be coordinated by Alexis Gaudin and will be carried out in collaboration with Christophe Blanquart (CRCINA, INSERM UMR 1232), Philippe Legrand (UMR 5253 CNRS- UM-ENSCM), Jeff Johnson (Cayman Chemical Company) and Stéphane Simon (University Paris Diderot (Paris VII). The specific goal of this project is to evaluate the potential benefits of a new biphasic microgel as lipoxin A4 (LXA4) delivery system for tissue engineering (pulp and periodontal tissue). The results of BILIPOX may provide a better understanding of microgels/macrophage interaction. This would be an important milestone for hydrogels modular strategy that open a new way to design and to multi-functionalize drug delivery systems.
