About this paper
Yijun Li, Stefan Stanojevic, Lana X. Garmire
This review article from the University of Michigan comprehensively surveys artificial intelligence methods, particularly deep learning, applied to spatial transcriptomics data analysis. It categorizes these approaches across five key analytical tasks, demonstrating how AI integrates gene expression with spatial information to overcome technical challenges and extract biological insights from complex tissue datasets.
Key insights
- Deep learning architectures, including autoencoders, convolutional neural networks (CNNs), and graph convolutional neural networks (GCNs), are predominantly used across all categories of ST analysis.
- AI methods are effectively addressing diverse ST challenges, such as identifying genes with non-random spatial patterns, grouping cells based on combined spatial-transcriptional profiles, and inferring cell-cell interactions.
- Multi-modal data integration, often combining ST data with histological images or single-cell RNA sequencing (scRNA-seq), is a consistent approach to enrich information and compensate for ST data limitations.
