By taking videos of a tiny beating zebrafish heart as it reconstructs its covering in a petri dish, scientists have captured unexpected dynamics of cells involved in tissue regeneration. They found that the depleted heart tissue regenerates in a wave, led by a front of fast-moving, supersized cells and trailed by smaller cells that multiply to produce others. The nature of this wavefront is determined by mechanical tension on the cells.
