We apply this method to visualize and measure mtDNA and heteroplasmy levels in situ at single-cell resolution in whole-mount Drosophila tissue and cultured human cells. In Drosophila, we identify a somatic mtDNA bottleneck during neurogenesis. This amplifies heteroplasmy variability between neurons, as predicted by a mathematical bottleneck model, predisposing individual neurons to a high mutation load.

High-resolution 3D imaging and spatial transcriptomics confirm these changes at the tissue level.
