Mechanisms of stem cell fate in tissue development, maintenance and disease

How do stem and progenitor cells regulate their fate behaviour to specify and maintain tissues? In development, tissue precursors must coordinate proliferation and differentiation with collective cell movements to specify organs of the correct size, pattern and composition. In the adult, stem cells must regulate a precise balance between proliferation and differentiation to maintain tissue homeostasis.

To address the mechanisms that regulate stem and progenitor cell fate, we combine cell lineage-tracing approaches and single-cell gene expression profiling with concepts and methods from statistical physics and mathematics. Applied to epithelial tissues, our studies have shown how common principles of self-organisation and emergence provide predictive insights into the cellular mechanisms that regulate tissue development and maintenance.

As well as questioning the basis of stem cell identity and the mechanisms that underpin cell fate stochasticity and state flexibility, these studies establish a quantitative platform to investigate pathways leading to tumour initiation and progression.
