Summary

The goal of our group is to bring together an interdisciplinary team of scientists to focus on the research of a particular complex system – development of the vertebrate limb. We aim to understand it both at the level of gene regulatory networks, and at the level of the physical interactions between cells and tissues.

To achieve this the group includes embryologists, computer scientists, imaging specialists and engineers. We thus aim to capture the whole process of understanding, from novel approaches for data-capture (live time-lapse OPT imaging) to finite-element simulations of the growing 3D structure and computer models of the gene networks responsible for pattern formation across the organ.

This combination of approaches is allowing us to address the following questions: What kinds of cellular movements are responsible for creating to correct 3D shape of the limb? How are these behaviours coordinated? How is the correct spatial pattern of gene expression controlled? What topology of gene regulatory network may be responsible for this complex phenomenon?

The fin-to-limb transition as the re-organization of a Turing pattern.

Onimaru et al. Nature Communications 7, 11582 doi:10.1038/ncomms11582

By combining experiments in shark embryos with computer modelling, we reveal that a Turing patterning network involving Bmp, Wnt and Sox9 is deeply conserved in skeletal patterning, all the way from sharks to mammals.

A Local, Self-Organizing Reaction-Diffusion Model Can Explain Somite Patterning in Embryos

Cotterell et al. Cell Systems 1(4) 257–269

By exploring dynamical computer models of somite patterning and then testing these ideas experimentally in chick embryos, we argue that the available data supports a Turing model just as strongly as the prevailing Clock & Wavefront model.
