Myriam Reffay's Group

Laboratoire Matière et Systèmes Complexes - UMR 7057

We are a young and dynamic group based in the Matière et Système Complexes laboratory in the heart of the Paris Rive Gauche district within the Université Paris Cité.

We study the mechanical properties of model tissues in the context of muscle differentiation and tumour progression. Our aim is to determine and understand the organisation and mechanics of these tissues, but also to be able to modify their fate by physical constraints.

RESEARCH INTERESTS

Architecture of model tissues under physical constraints, Mechanobiology of model tissues, Multicellular communication and dynamics, Muscle cell differentiation, Tumoral progression.

TOOLS

Magnetic nanoparticles, multicellular aggregates, manipulation of magnetic aggregates, tissue rheology, tissue microscopy, 2-photons microscopy.

Research Interests

Magnetic multicellular aggregates
Stretching muscle precursor to differentiate them
Macroscopic mechanical properties
