Area of Science:

Computational biology
Genomics
Immunology

Background:

Single-cell RNA sequencing (scRNA-seq) enables discovery of novel cell populations.
Identifying reliable gene marker panels for these cell populations is crucial but challenging.
Existing methods struggle with comprehensive marker panel identification.

Purpose of the Study:

Introduce COMET, a computational framework for identifying gene marker panels.
Enable prediction of single- and multi-gene marker panels from scRNA-seq data.
Validate COMET's accuracy and applicability for cell population characterization.

Main Methods:

Developed COMET, a non-parametric statistical framework.
Applied COMET to single-cell RNA-seq datasets.
Validated predictions using flow cytometry assays.

Main Results:

COMET outperforms existing methods in identifying single-gene marker panels.
COMET is the first framework to predict ranked multi-gene marker panels.
Experimental validation confirmed COMET's accuracy for single- and multi-gene panels.

Conclusions:

COMET accurately identifies gene marker panels for cell populations from transcriptomic data.
The framework supports both single- and multi-gene panel prediction.
COMET is a versatile tool applicable to various high-throughput datasets.
