Genetic analysis of epidermal cell adhesion in the developing zebrafish

Cell Biology

We use zebrafish as a model organism to investigate the developmental and cellular mechanisms involved in the establishment as well as maintenance of the epidermal architecture and integrity. We combine genetic approaches with confocal microscopy to unravel the importance of cell size, cell shape, cell polarization and cell adhesion in epidermal morphogenesis. In addition, we are interested in understanding how the changes in cell size or cell-polarity lead to re-calibration of tissue homeostasis or to epidermal hyperplasia.
