Protocol for live-cell imaging of mitochondrial dynamics in adult Drosophila oenocytes

Mitochondrial dynamics are essential for cellular homeostasis and can be visualized in adult Drosophila oenocytes using live-cell confocal imaging. Here, we present a protocol for live-cell imaging of mitochondrial dynamics in adult Drosophila oenocytes. We describe steps for fly preparation, dissection of abdominal cuticle to expose oenocytes, and mounting. We then detail procedures for time-lapse acquisition of mitochondria labeled with mitoGFP. Optimized imaging parameters enable reproducible visualization of mitochondrial morphology stably for longer durations.
