Background:

Understanding cell-cell interactions is crucial for disease and tissue biology.
Current methods for analyzing cell colocalization obscure molecular signatures of intercellular communication.

Purpose of the Study:

To introduce DeepCOLOR, a novel computational framework for recovering intercellular colocalization networks at single-cell resolution.
To overcome limitations of existing methods that rely on predefined cell populations.

Main Methods:

Development of DeepCOLOR, a deep generative model.
Integration of single-cell and spatial transcriptomics data.
Analysis of colocalization patterns in simulated and real biological datasets.

Main Results:

DeepCOLOR demonstrated superior accuracy in detecting colocalized populations compared to existing methods on simulated data.
Identified plausible cell-cell interaction candidates in mouse brain, human squamous cell carcinoma, and SARS-CoV-2 infected human lung tissues.
Revealed colocalization relationships between single cells and segregated cell populations.

Conclusions:

DeepCOLOR effectively recovers intercellular colocalization networks with single-cell resolution.
The framework is broadly applicable to studying cell-cell interactions across diverse spatial niches.
DeepCOLOR enhances the understanding of biological functions in diseases and tissues through detailed interaction analysis.
