Background:

Spatially resolved transcriptomics (SRT) provides unprecedented insights into cellular organization within tissues.
Current SRT data analysis predominantly relies on single-cell RNA sequencing (scRNA-seq) tools, which may not fully capture SRT-specific properties.
The integration of spatial location and histological data with gene expression remains an underexplored area.

Purpose of the Study:

To review statistical and machine learning approaches tailored for spatially resolved transcriptomics data analysis.
To explore the integration of spatial location and high-resolution histology information with gene expression data.
To highlight advancements and identify future research directions in SRT data analysis.

Main Methods:

Review of existing statistical and machine learning methodologies applicable to SRT.
Discussion on integrating spatial coordinates and histological features into gene expression analysis.
Identification of challenges and opportunities in SRT data interpretation.

Main Results:

SRT data possess unique characteristics distinct from scRNA-seq data, necessitating specialized analytical methods.
Spatial and histological information can significantly enhance the understanding of transcriptional complexity.
Current analytical tools are often insufficient for fully leveraging the spatial dimension of SRT.

Conclusions:

Developing novel statistical and machine learning methods is crucial for advancing SRT data analysis.
Integrating spatial and histological data holds great potential for uncovering novel biological insights.
Further research is needed to address open problems and fully exploit the capabilities of SRT technologies.
