Background:

Spatial transcriptomics technologies like MERFISH offer high-resolution cellular data.
Analyzing this complex data requires advanced computational tools to identify subcellular patterns.

Purpose of the Study:

To introduce the Intracellular Spatial Transcriptomic Analysis Toolkit (InSTAnT).
To enable the extraction of molecular relationships from spatial transcriptomics data at single-molecule resolution.

Main Methods:

InSTAnT utilizes specialized statistical tests and algorithms.
The toolkit detects gene pairs and modules with co-localization patterns within and across cells.
Validation performed on diverse datasets from different cell lines, species, and technologies.

Main Results:

Identified cell type and region-specific gene co-localizations in brain tissue.
Discovered intra-cellular spatial patterns reflecting RNA interactions and shared subcellular functions.
Validated findings using external databases and RNA interaction data.

Conclusions:

InSTAnT effectively reveals subcellular molecular relationships from spatial transcriptomics data.
The toolkit generates testable hypotheses for molecular functions and interactions.
Facilitates deeper understanding of cellular organization and gene expression patterns.
