Abstract
This protocol describes the preparation of Drosophilamelanogaster pupae for laser ablation and live imaging of the notum (dorsal thorax). Because the pupa is stationary, it can be continuously live imaged for multiple days if desired, making it ideal for studying wound signaling and repair, from before laser ablation through wound closure. In this protocol, we demonstrate the processes of staging, partially dissecting, mounting, wounding, and live imaging the pupal notum, with the wounding occurring during the live imaging process.
For complete details on the use and execution of this protocol, please refer to O’Connor et al. (2021b).
The Drosophila pupa is an attractive model to study wound repair in vivo
The dorsal thorax epithelium is accessible after partial dissection of the pupal case
Pupae are mounted on a cover glass and wounded by laser ablation
Pupae are imaged live during wounding through wound closure to analyze signaling/repair
Publisher's note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
