Launching of the INSERM French network : NetwOArk

RMES is happy to announce the launching of the INSERM French network dedicated to peripheral and spine osteoarthritis : NetwOArk. Jerome Guicheux will serve NetwOArk as national coordinator with Francis Berenbaum as a co-coordinator. NetwOArk aims bringing together all the scientific actors involved in osteoarthritis research in order to federate and promote the emergence of high-level scientific works in this field. NetwOArk is created for 4 years and is supported by INSERM, Aviesan and ITMO PMN. NetwOArk is organized around 4 work packages coordinated by Claire Vinatier and Esther Potier (WP 1 pathophysiology), Khorng Ea and Yves-Marie Pers (WP2 disease bio markers), Christelle N’Guyen and Jeremy Sellam (WP3 prevention and treatment) and David Moulin and Emeline Perrier-Groult (WP4 innovation). A first scientific event will be organized in 2020 to gather the French actors involved in Osteoarthritis research. We hope to meet you all to share recent advances in basic, translational and clinical research dedicated to this incurable and disabling disease.

New funding of BIOREGATE

The STEP team (UMR 1229 INSERM-Nantes University-ONIRIS) is pleased to announce that the project DISCODOG was awarded of BIOREGATE (Région Pays de la Loire) grant (veterinary clinic grant). The project is led by Johann CLOUET and Marion FUSELLIER. This project will be performed in collaboration with the MINT laboratory (INSERM 1066 CNRS 6021) in Angers (Elise LEPELTIER).The two objectives of DISCODOG are to develop a new therapeutic tool to treat discogenic lumbalgia, consisting in miRNA encapsulated in lipid nanocapsules and to validate a new method to detect early signs of disc degeneration in canine patients. After intradiscal injection in clinic dogs, security and efficacy of the treatment will be followed by the mean of orthopedic and neurologic examination as well as by MRI, during 6 months. 120 k€ will be dedicated to the DISCODOG project during 2 years. The project will begin during the first semester of 2020..

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. .

Visit of the Scientfic Advisory Board (SAB)

The RMeS SAB meeeting took place on November 14th, 2019 in Nantes. Reports and projects of our two teams (ReJoint and RegOs) were presented to the members of the SAB : Profs. D. Mantovani, R. Baron & D. Mainard. Overall, SAB members were particularly impressed by our work and research facilities. Their strong expertise and advice will be highly beneficial for our present and futur projects.
