Within the embryos, cells interact with each other, exchanging chemical and mechanical information. One efficient way of probing these interactions is to kill some cells and monitor the consequences on neighboring cells. The method we describe all

Embryonic development requires large-scale coordination of cell motion. Two-photon excitation mediated laser ablation allows the spatially controlled 3-dimensional ablation of large groups of deep cells. In addition, this technique can probe the reaction of collectively migrating cells in vivo to perturbations in their mechanical environment.
