Research summary

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? During development, cell proliferation and differentiation must be coordinated 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.

Expand summary

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, we have shown how common principles of self-organisation and emergence provide predictive insights into the cellular mechanisms that regulate tissue development, maintenance and repair.

As well as questioning the nature of stem cell identity and function, these studies emphasize the role of cell fate stochasticity and state flexibility, and establish a quantitative platform to investigate pathways leading to cancer initiation and progression.
