HaDM-ST: Histology-Assisted Differential Modeling for Spatial Transcriptomics Generation
Xuepeng Liu, Zheng Jiang, Pinan Zhu +2
Spatial transcriptomics (ST) reveals spatial heterogeneity of gene expression, yet its resolution is limited by current platforms. Recent methods enhance resolution via H&E-stained…
