arXiv:2603.13432v4 Announce Type: replace-cross Abstract: Spatial Transcriptomics (ST) profiles thousands of gene expression values at discrete spots with precise coordinates on tissue sections, preserving spatial context essential for clinical and pathological studies. With rising sequencing throughput and advancing platforms, the expanding data volumes motivate large-scale ST pretraining. However, the fundamental unit for pretraining, i.e., what constitutes a single training sample, remains ill-posed. Existing choices fall into two camps: (1) treating each spot as an independent sample, whic
Advances in sequencing throughput and spatial transcriptomics platforms are generating unprecedented data volumes, creating an urgent need for efficient large-scale pretraining methodologies to unlock their full potential.
This development proposes a new fundamental unit for pretraining spatial transcriptomics data, addressing a critical bottleneck that could accelerate drug discovery, diagnostics, and fundamental biological understanding.
The proposed 'pretext task' approach, leveraging spatial and gene expression information as images, could lead to more robust and generalizable models for analyzing complex tissue environments.
