HESpotEx: a dual-stream deep learning framework for spot-level gene expression prediction from histological images
AI trained on routine tissue slides can predict which genes are active in tumors without expensive genetic sequencing, democratizing molecular diagnostics.
HESpotEx uses a graph attention autoencoder + CNN decoder architecture to predict spatial transcriptomic profiles of up to 5,457 genes from routine histology slides, without expensive spatial RNA sequencing. Validated on TCGA and multiple cancer tissue types including lymphoma, it could democratize spatial molecular characterization of tumors.
