Could macrophages inadvertently stimulate cancer cells growth with no biochemical enrolment ? We show here how it could happen, in a study involving experiments performed in Institut Curie, theoretical physics and simulations !

What would be the physical models of 3d multicellular aggregates ? We describe in this review the different approaches, develop a continuous formalism, and apply it in a series of interesting cases.

Mechanical stresses are crucial in stem cell differentiation. We use a morphoelastic framework to quantify stresses in constrained proliferation of stem cell cysts inside alginate capsules, in collaboration with the startup TreeFrog Therapeutics. By the way, we infer the mechanical properties of those biological shells, and how growth itself is controlled by mechanical stresses. Published in JMPS.
