Abstract The current challenge in analyzing sequencing-based spatial transcriptomics (ST) is to precisely resolve the distribution of cell subpopulations with low abundance and detect context-dependent variation states within complex tissue microenvironments. Here, we introduce an ultra-resolution ST deconvolution algorithm (UCASpatial) that improves resolution mapping locations by leveraging contribution genes indicative identity through entropy-based weighting. Using both silico real datasets, demonstrate UCASpatial robustness accuracy identifying low-abundant distinguishing transcriptionally heterogeneous subpopulations.
