Background:

Spatial transcriptomics (ST) offers low-resolution tissue-wide gene expression data.
Single-cell RNA sequencing (scRNA-seq) provides high-resolution but spatially unmapped gene expression profiles.
Integrating scRNA-seq and ST data is crucial for comprehensive biological insights.

Purpose of the Study:

To develop a computational method for accurate mapping between scRNA-seq and ST data.
To enable the deconvolution of cell types within ST spots.
To assign spatial coordinates to individual cells from scRNA-seq data.

Main Methods:

Developed Celloc, a novel method utilizing a graph attention autoencoder.
Incorporated comprehensive loss functions for flexible single cell-to-spot mapping.
Benchmarked performance on simulated and real scRNA-seq and ST datasets.

Main Results:

Celloc demonstrated superior accuracy and robustness over existing state-of-the-art methods on simulated data.
Evaluations on real datasets showed Celloc's capability to reconstruct cellular spatial structures.
Successfully applied to diverse tissues and histological regions, identifying various cell types.

Conclusions:

Celloc effectively bridges the resolution gap between scRNA-seq and ST data.
The method provides a powerful tool for dissecting cellular composition and spatial organization in tissues.
Celloc facilitates a deeper understanding of tissue architecture and cell-cell interactions.
