Area of Science:

  • Genomics and Bioinformatics
  • Cell Biology
  • Computational Biology

Background:

  • Single-cell and spatial omics advance cellular heterogeneity studies.
  • Existing methods struggle to find specific molecular features for experimental applications.

Purpose of the Study:

  • Develop a novel computational method, CSFeatures, to identify cell-type-specific molecular features.
  • Enable accurate cell population characterization and downstream applications.

Main Methods:

  • CSFeatures integrates expression, distribution, and proportional representation.
  • Evaluated on simulated and 14 real datasets (scRNA-seq, scATAC-seq, ST, spaATAC-seq).
  • Validated findings at the protein level using multiplex immunofluorescence.

Main Results:

  • CSFeatures reliably identifies highly specific cell-type markers.
  • Identified markers are enriched in relevant cellular pathways and functions.
  • Protein-level validation confirms applicability for cell sorting and diagnostics.
  • Successfully applied to diverse omics data, revealing gene regulation and spatial insights.

Conclusions:

  • CSFeatures improves identification of cell-type-specific features from multi-modal omics data.
  • Provides high-fidelity markers for accurate cell population characterization.
  • Facilitates deeper mechanistic investigations in experimental and clinical settings.
