Area of Science:

Molecular Biology
Genomics
Bioinformatics

Background:

Spatial transcriptomics enables understanding tissue organization and cell interactions.
Current platforms often lack cellular resolution, limiting insights.
Emerging sub-cellular resolution technologies face challenges in cell segmentation and spot assignment.

Approach:

We introduce SCS, a novel method combining imaging and sequencing data for enhanced cell segmentation.
SCS utilizes a transformer neural network to learn spot positions relative to cell centers.
The approach was validated on two sub-cellular spatial transcriptomics technologies.

Key Points:

SCS significantly outperforms traditional image-based segmentation methods.
Achieved higher accuracy, identified more cells, and provided more realistic cell size estimations.
Enables sub-cellular RNA localization analysis, supporting segmentation accuracy.

Conclusions:

SCS advances cell segmentation for sub-cellular spatial transcriptomics.
Improves the analysis of RNA localization within cells.
Facilitates deeper understanding of cellular architecture and function.
