New funding of FNSRS & ANR

The STEP team is pleased to announce that the INDEED project (International Collaborative Research Project - PRCI) led by Matteo D'Este (AO Research Institute, Switzerland) and Christophe Helary (UMR 7574, Sorbonne University- CNRS, France) in partnership with RMeS (INSERM U1229-ONIRIS-Nantes University, France) and the Biomechanical Institute (ETH, Switzerland) has been selected for funding by the Swiss national fund for scientific research (FNSRS) and the french research agency (ANR). The main objective of INDEED is to develop a 3D model of intervertebral disc (IVD) by bio-impression. Composite inks based on hyaluronic acid and collagen will be synthesized (UMR 7574) and their interactions with IVD cells will be characterized (UMR 1229). The mechanical (ETH) and biological (ARI) properties of this bio-printed IVD will be compared to those of animal and human discs. This disc model will also be used to decipher the molecular mechanisms of disc degeneration at the origin of low back pain but also for the screening of new therapeutic agents, thus contributing to reduce the use of animal experiments.

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.

New funding of NExT

The STEP team of the INSERM U1229-RMeS laboratory is pleased to announce the success of the SHELBY project in phase 2 of the NExT IIP (Internal interdisciplinary projects) call of proposals. The laboratory will receive a grant of 140 k€ for 3 years to hire dedicated staff (PhD student or engineer). The SHELBY project will be coordinated by Catherine Le Visage and will be carried out in collaboration with Denis Renard (INRA BIA) and Arnaud Teissier (CEISAM, CNRS). The objectives of this project are to develop innovative hydrogels for stem cell encapsulation by lithography, with particular application to cell therapy of disc or peripheral osteoarthritis.
