Histopathology, particularly hematoxylin and eosin (H\&E) staining, plays a critical role in diagnosing characterizing pathological conditions by highlighting tissue morphology. However, H\&E-stained images inherently lack molecular information, requiring costly resource-intensive methods like spatial transcriptomics to map gene expression with resolution. To address these challenges, we introduce HECLIP (Histology-Enhanced Contrastive Learning for Imputation of Profiles), an innovative deep...
