Repair and regeneration: how cells repair and replace themselves – Video 2

Following tissue damage, a complex repair process is initiated to restore the integrity of the injured tissue; re-epithelialization is accompanied by a rapid inflammatory response as innate immune cells are rapidly recruited to the damaged area. Here, we exploit the optical translucency and genetic tractability of Drosophila pupae to follow both of these processes over 2 hours using confocal imaging in vivo. Following laser-induced damage to the pupal wing epithelium (green GFP-tagged E-cadherin), Drosophil
