Missing data in single-cell transcriptomes reveals transcriptional shifts

Profiling thousands of single cell transcriptomes is routine, yet cell prioritization based on response to biological perturbations is challenging and confounded by clustering, normalization and dimensionality reduction strategies. We developed a scoring approach independent of these obstacles that unbiasedly identifies distinct transcriptomes within a set based on missing data patterns, allowing cell prioritization and feature selection for downstream analysis. Our method applied to D. discoideum reveals a metabolic shift that marks the transition between the amoeboid and aggregated states of this model organism.
