Preclinical


With its significant contributions in over 20 national and European clinical trial programs using mesenchymal stem cells (MSC), ECellFrance has acquired a large amount of data, experience, models, and tools specific to preclinical study of MSC-based products.


The preclinical platforms gather the knowhow, data and tools for biodistribution and toxicology studies specific to MSC. They are located in Montpellier, Toulouse, Clamart, and Grenoble. Each platform has its specificities in terms of equipments and fields of expertise to address, altogether, a wide range of possible applications.

    • arthritis (CIA/AIA/Ab-induced mouse)
    • osteoarthristis (CIOA/DMM mouse)
    • scleroderma (HOCl mouse)
    • colitis (TH cells, Rag-/- mouse)
    • delayed hypersensitivity (OVA induced DTH mouse)
  • Cadiovascular disease (Toulouse)
    • Lower limb ischemia mouse model
