Area of Science:

Spatial transcriptomics (ST) and computational biology.
Single-cell genomics and bioinformatics.
Biomedical data analysis and interpretation.

Background:

Spatial transcriptomics (ST) enables tissue architecture and function studies.
Low resolution of ST limits cell-type deconvolution from spatial mixtures.
A comprehensive evaluation of existing ST deconvolution methods is lacking.

Purpose of the Study:

To benchmark 14 ST deconvolution methods across four datasets.
To assess method robustness against sequencing depth, spot size, and normalization.
To develop an improved deconvolution method, EnDecon.

Main Methods:

Benchmarking 14 deconvolution algorithms on diverse ST datasets.
Evaluating performance using RMSE, PCC, and JSD metrics.
Developing an ensemble learning-based deconvolution method (EnDecon).

Main Results:

cell2location, RCTD, and spatialDWLS demonstrated superior accuracy.
cell2location and spatialDWLS showed greater robustness to sequencing depth variations.
Method accuracy generally decreased with smaller spot sizes.
EnDecon achieved more accurate deconvolution by integrating multiple methods.

Conclusions:

Provides a comparative analysis and guidelines for selecting ST deconvolution tools.
Highlights the performance variations and robustness of different deconvolution methods.
Introduces EnDecon as a promising approach for enhanced spatial transcriptomics deconvolution.
