I carry out an optical-based manipulation method to impose different force patterns on cell contacts in the early epithelium of the Drosophila embryo. The method relies on dual-optical traps, which tweeze two distinct junctions to generate a deformation on an adjacent junction. I found different mechanical response depending on whether the manipulated junctions belonged to the same cell or to two cells sharing a junction. I have also found that direct manipulation of both vertices of a junction can cause the junction to shrink completely. To understand the molecular origin of such deformations, I monitored, during the manipulation, the distribution of junctional constituents, including the adhesion protein E-Cadherin, actin and Myosin-II. The observed changes in the molecular distribution reveal feedbacks that depend on the modes of deformation.
