Area of Science:

Computational pathology
Spatial statistics
Bioinformatics

Background:

Understanding tissue microenvironments is vital for cell communication and molecular signaling.
Current digital pathology image analysis methods for spatial relationships are limited and often restricted to specific outcomes or field-of-view analyses.
Existing methods struggle to capture complex spatial patterns across whole-slide images.

Purpose of the Study:

To introduce SpatialQPFs, an R package for extracting interpretable spatial features from cell imaging data.
To provide a comprehensive toolkit for applying diverse spatial statistical methodologies within a stochastic process framework.
To enable thorough, large-scale spatial analyses applicable across various clinical and biological contexts.

Main Methods:

Leveraging segmented cell information to extract spatial features.
Applying spatial statistical methodologies including point process, areal data, and geostatistical analyses.
Utilizing a stochastic process framework for robust spatial analysis.

Main Results:

SpatialQPFs decouples feature extraction from specific outcome models, allowing for flexible and independent spatial analyses.
The package enhances the depth, accuracy, and reproducibility of spatial insights from tissue data.
Facilitates efficient and comprehensive spatial analyses for researchers.

Conclusions:

SpatialQPFs offers a flexible and robust framework for advanced spatial feature extraction in tissue biology and pathology.
Empowers researchers to conduct detailed spatial analyses, leading to new discoveries.
Publicly available code and documentation promote reproducible research in spatial biology.
