Experimental and computational analysis of tissue elongation


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. The Green lab’s embryonic cell self-elongating aggregate method will be used to test the engineering parameters of elongation compared with those of a computer model developed by the Miodownik group to test our assumptions and improve our understanding of tissue-shaping processes in vivo
