Meeting report – CellExIt#1, the first international symposium on cell extrusion

In April 2026, the first international symposium on cell extrusion (CellExIt#1) was held in St Jean-Cap-Ferrat in the south of France. The meeting gathered investigators who, through different perspectives and disciplines, are dissecting the mechanisms leading to the seamless expulsion of cells from epithelial tissues. In this Meeting Report, we provide a brief overview of cell extrusion as well as a panoramic view of the research on this crucial physiological process that has recently been performed in the different laboratories represented at CellExIt#1, outlining ongoing projects, the diversity of experimental angles and important open questions in the field.
