Guillaume Salbreux – Lecture “Connecting scales in tissue morphogenesis”

Lecture given by Prof. Dr. Guillaume Salbreux (University of Geneva, CH) during the 4th international course on Multiscale Integration in Biological Systems (Institut Curie, November 4-10, 2021).

One of the fundamental issues in biology is the understanding of the relationship between the multiple spatial and temporal scales observed in a biological system. From molecules to a cellular function, from a collection of cells to an organism, or from individuals to a population, the complex interactions between singular elements can give rise to “emergent” properties at the ensemble level. To what extent can the spatial and temporal order seen at the system level be explained by subscale properties?

This course provided an overview of modern physical tools that have been developed to address the issue of scale integration (morning lectures), including examples of research that applies such tools to specific biological systems (afternoon conferences).
