Cell-to-cell variability is an inherent feature of cell populations and multicellular organisms. Such plasticity is essential for embryo  development and serves as a mechanism of tissue regeneration but it can also predispose tissues to malignant transformation. How cell heterogeneity emerges during development and contributes to disease is a fundamental question in biology.
In the laboratory we are interested in determining the roles of cell heterogeneity in development and regeneration, and are exploring strategies to unlock phenotypic plasticity in pluripotent and cancer cells.

Common Mechanisms of Cell Plasticity in Development and Cancer

Cell heterogeneity not only arises from the coexistence of different cell subsets, but also from cells alternating between interconvertible metastable states. The main source of such plasticity is the Epithelial-Mesenchymal Transition (EMT) that is not confined to physiological embryonic development but is reactivated at the onset of several pathologies, including tumor progression/metastasis and fibrosis.

In the laboratory we use different strategies based on development-inspired cues and unbiased high-throughput phenotypic screenings to investigate the mechanisms that control phenotypic plasticity in stem cell population and cancer cells. We also use 3D gastruloids and tumour organoids to study how cell heterogeneity influences the self-organization properties of stem cells.

Cell Hetherogeneity in Skeletal Muscle Regeneration

Skeletal muscle has a remarkable regenerative capacity that relies on highly coordinated interactions of different cell populations, including muscle stem cells/satellite cells, macrophages and endothelial progenitors. In chronic muscle disorders and in aging this repair mechanism does not work properly and the damage cannot be resolved, resulting in severe muscle wasting and prolonged functional disability.

We are investigating the role of the TGFß ligand coreceptor Cripto in this complex scenario, and in particular in the cellular and molecular mechanisms that link inflammation and regeneration, which still remain largely unclear. https://renoir-itn.eu/
