TITLE: Evolution of mesendoderm patterning in echinoderm embryos.
ABSTRACT: Vanessa Barone studied molecular biology at the University of Turin, Italy and then pursued her PhD in the Carl-Philipp Heisenberg group at the Institute of Science and Technology Austria in Vienna. There she investigated how cell-cell contacts regulate cell differentiation of mesendodermal progenitors during zebrafish gastrulation, finding a positive feedback loop between cell-cell contacts and Nodal signalling that determines cell fate decisions. This opened an evo-devo question: may regulatory interactions between cell adhesion and cell signalling underlie evolutionary changes in tissue patterning? To address this question, Vanessa moved to echinoderm embryos and joined Deirdre Lyons group at the University of California San Diego, where she is using the sea urchin and sea star embryos to investigate the role of cell-cell contacts in the evolution of mesendodermal tissue patterning.
