The Chow group is interested in the study of heart valve development, disease, and regeneration. The lab develops novel micromanipulation methods to perturb mechanical forces in the zebrafish heart and combines these methods with computational modelling, live imaging, and genetics to uncover the role of mechanical signals caused by heartbeat and blood flow on heart valve biology.


Video above: Blocking blood flow by inserting a bead into the heart stops the valve leaflet from being released during embryonic development. Note that the valve leaflet opens and closes during heartbeat in the control embryo (left panel) but remains stuck to other cells in embryos where a bead has been inserted.
