Using stem cells to regenerate tissues requires that we know how tissues are built up in normal development. We have previously shown that tissue growth – specifically elongation – involves not just proliferation but also cell shape change and rearrangement. To understand these processes better, this project is to analyse the self-organisation of cell aggregates both in vivo and in silico. This is a form of synthetic biology at the cellular level.
