abstract = {While heterogeneity is a key feature of cancer,
understanding metabolic heterogeneity at the single-cell
level remains a challenge. Here we present 13C-SpaceM, a
method for spatial single-cell isotope tracing that extends
the previously published SpaceM method with detection of
13C6-glucose-derived carbons in esterified fatty acids. We
validated 13C-SpaceM on spatially heterogeneous models using
liver cancer cells subjected to either normoxia-hypoxia or
ATP citrate lyase depletion. This revealed substantial
single-cell heterogeneity in labelling of the lipogenic
acetyl-CoA pool and in relative fatty acid uptake versus
synthesis hidden in bulk analyses. Analysing tumour-bearing
brain tissue from mice fed a 13C6-glucose-containing diet,
we found higher glucose-dependent synthesis of saturated
fatty acids and increased elongation of essential fatty
acids in tumours compared with healthy brains. Furthermore,
our analysis uncovered spatial heterogeneity in lipogenic
acetyl-CoA pool labelling in tumours. Our method enhances
spatial probing of metabolic activities in single cells and
tissues, providing insights into fatty acid metabolism in
homoeostasis and disease.},
