Post-doc position on notochordal differentiation and stem cell-based therapy for intervertebral disc degeneration (starting from March 2019)

We recruit

A 24 months-postdoctoral position (funded by H2020 European research project iPSPINE,Coord. Marianna Tryfonidou, The Netherlands) working on iPS differentiation and regenerative medicine is available, starting from March 2019 in our research lab. Human iPSC maintenance and production will be performed in close collaboration with the DeviPS core facility (SFR François Bonamy, INSERM UMS 016, Nantes University), which is coordinated by the Dr. Laurent David (a specialist of somatic cell reprogramming, MCU-PH and coordinator of the platform). Selected candidate will work under the supervision of Dr Anne Camus, leader of “Stem Cells and Axial Skeleton Development” project in the team “skeletal physiopathology and joint regenerative medicine” headed by Jerome Guicheux. Applicants are invited to send a CV with skills and complete list of publications, a cover letter including a brief statement of past scientific experiences, achievements, name and email address of 2-3 references to Anne CAMUS, Jerome GUICHEUX and Laurent DAVID. Our job offer can be downloaded here !

H2020An additional Horizon 2020 European research grant for INSERM UMR 1229-RMeS towards treating chronic back pain

In 2016, the European commission invested 5.5 millions Euros in the RESPINE project to clinically address whether bone marrow-derived mesenchymal stromal cells may help solve low back pain that affects hundreds of millions of patients worldwide. The double blind phase 2b RESPINE clinical trial (P.I. Christian Jorgensen, Montpellier University Hospital; EudraCT 2017-002092-25) is now recruiting more than 100 patients in France and European countries. Jerome Guicheux (Nantes scientific coordinator, STEP Team, INSERM UMR 1229-RMeS) is a task leader in this project in charge of developing cutting-edge potency assays for the preclinical evaluation of the regenerative potential of stem cells (Cécile Boyer). Fifteen patients will be recruited at the Nantes University Hospital in the department of neurotraumatology and neurosurgery (Eric Bord). After the successful funding of RESPINE, the STEP team of the INSERM UMRS 1229-RMeS is now pleased to announce the recent selection of the H2020 iPSpine project by the European commission. iPSpine will receive an overall grant of 15 M€. This large European consortium will gather 20 international partners and will be coordinated by Marianna Tryfonidou (Utrecht University, The Netherlands). This project will officially be launched in February 2019 and it will deal with the development of advanced therapy medicinal products based on the use of biomaterials and induced-pluripotent stem cells (iPSC) towards solving intervertebral disc (IVD) degeneration. Jerome Guicheux is the scientific coordinator of iPSpine workpackage (WP) 1 “iPSC development, differentiation and technologies” that gathers 7 international partners and focus on discovering innovative culture protocols for the generation of IVD cells derived from human iPSC (Anne Camus). In collaboration with the ONIRIS-national veterinary school of Nantes, the STEP team will also participate in WPs 3 and 6 respectively dedicated to (i) in vitro 3D cell culture (Catherine Le Visage, RMeS) and (ii) the first canine clinical trial related to the efficacy of the intradiscal injection of iPSC-derived regenerative cells in the treatment of low back pain (Marion Fusellier & Johann Clouet). RMeS will receive a global support of about 1.3 million Euros and will recruit 1 post-doc, 2 research assistants and 1 clinical assistant.

FRMFRM announcement

The STEP team is pleased to announce the funding of Vianney Delplace’s position by the Fondation pour la Recherche Médicale (FRM) for 3 years. Using his expertise in hydrogel design, Vianney Delplace will develop innovative intra-articular cell therapies for the treatment of osteoarthritis, under the supervision of Catherine Le Visage and Jérôme Guicheux. In collaboration with Arnaud Tessier from the CEISAM laboratory (UMR CNRS 6230, Nantes), a new class of self-healing hydrogels will be designed to best mimic the biomechanical properties of native cartilages and deliver anti-inflammatory factor secreting stem cells.
