WEEKLY EPFL BIOE TALKS SERIES
Abstract:
Multicellular organisms are composed of cells and tissues with identical genomes but different properties and functions. They all develop from one cell to form multicellular structures of astounding complexity. During development, in a series of spatio-temporal coordinated steps, cells differentiate into different cell types and establish tissue-scale architectures and functions. Throughout life, continuous tissue renewal and regeneration is required for tissue homeostasis, which also requires fine-tuned spatio-temporal coordination of cells. I will discuss how cellular interactions generate the specific contexts and spatio-temporal coordination underlying development and regeneration and how we specifically investigate what are the molecular and physical mechanisms that allow a cell, in a tissue, to sense its complex environment, to take individual coordinated decisions. Moreover, I will discuss the molecular mechanisms of intestinal organoid self-organization and the role of cell-to-cell variability in populations of differentiating cells during symmetry breaking.
Bio:
Prisca Liberali has been trained as a physical organic chemist with a focus on the dynamical understanding of organic chemical reactions. She then changed fields for her PhD and became a molecular cell biologist. She has developed single-cell methods to study cell-to-cell variability and its involvement in the emergence of complex cellular traits. Since a few years she has become fascinated by the role of self-organisation in collective cell behaviours, and how these can control intracellular signalling in single cells. Because these emergent phenomena have multiple layers of biological organisation at different scales, she believes that novel experimental, quantitative and statistical methods are required to integrate our understanding of single-cell biology. Currently, she is a professor at the Friedrich Miescher Institute (FMI) with a lab focused on dynamics of self-organisation, and on how cellular signalling dictates its spatial-temporal regulation.
