Títol: Searching for all gene networks capable of pattern formation.

Resum: Development is the process by which the complex anatomy of multicellular organisms is built in each generation. Not many other natural processes lead to so much complexity in such a short period of time.
Morphological transformations during development are regulated by what we call gene regulatory networks, that is, the specific activatory and inhibitory interactions between gene products at a molecular level. In this talk, under the framework of reaction-diffusion models, we attempt a mathematical approach to these developmental transformations by asking ourselves a very simple question: “which gene regulatory networks are actually capable of pattern formation?” More specifically, we wonder whether the immense number of patterning gene networks that we can think of – especially when the number of genes involved in the network is very large – can all be sorted into some few fundamental classes sharing the same topological features and resulting in similar final patterns.
