Our research

Our research studies the cellular, molecular, and mechanical mechanisms of coordinated migration, in which cells are physically and/or functionally connected, using the early mouse embryo as a model.

Collective migration is essential for morphogenetic movements during embryogenesis, as well as for major physiological (such as wound healing) and pathological (such as cancer invasion) processes during adult life. The peri-gastrulation mouse embryo is a relatively simple structure composed of a limited number of distinguishable cell types, wich allows studying specific cell populations in their physiological context.

In particular, we focus on  Anterior Visceral Endoderm migration as a model of epithelial collective migration, and Mesoderm migration as a model of epithelial-mesenchymal transition followed by cell sheet migration. We use quantitative live imaging and transcriptomics to decipher the determinants of early morphogenesis, the ultimate goal being to reproduce in vitro the extracellular milieu that will drive endoderm and mesoderm cells towards a particular fate.

Jessica Mathiah – PhD student

Navrita Mathiah received a master degree in Biomedical Sciences in 2012 from the Universite Libre de Bruxelles (ULB). After performing a master thesis in Cédric Blanpain’s lab, Navrita joined the laboratory in October 2012 to begin a PhD program and is a recipient of the FRIA/FNRS research fellowship.Her work aims to better understand the molecular and cellular events leading to primitive streak and mesoderm layer formation during mouse embryonic development.

Bechara Saykali – PhD student

Bechara Saykali received his Masters in Molecular and Cell Biology from the Lebanese American University in 2013. During his master’s, he studied cell motility in cancer and the role of Rho GTPases in metastasis. He joined our Lab in 2014 as a PhD student after acquiring a scholarship awarded By Phoenix, Erasmus Mundus. He then received a FRIA scholarship, awarded by FNRS. Bechara is currently working on characterizing mesoderm development in mouse embryos.

Wallis Nahaboo, PhD – postdoctoral fellow

After completing her biomedical engineer diploma (PHELMA, Grenoble INP), Wallis started her Phd in Delattre lab in ENS Lyon, France.She worked on the forces that drive chromosome segregation in C. elegans embryos. Wallis is interested in studying live cell dynamics and specifically the cytoskeleton.Just after her PhD defence, in April 2016, she joined our lab as a postdoc. She is currently working on cell migration in mouse embryos development: She focuses on quantitative analysis of imaging data, as well as develops tools to study mechanical forces in the gastrulating embryo.
