By integrating gene expression with high-resolution histology images, SpaHDmap builds biologically interpretable embeddings and enables joint modeling across slices and samples. Validated on real and simulated datasets, it consistently recovers fine spatial structures that conventional methods miss.

🧬What if you could dissect gene activity at near-cellular resolution?

Prof. Xi Ruibin and colleagues at PKU’s School of Mathematical Sciences introduce SpaHDmap, an interpretable multimodal framework for spatial transcriptomics.
