Spatial multi-omics uncovers an invasive-desmoplastic cellular community with prognostic and therapeutic implications in pancreatic ductal adenocarcinoma
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dense desmoplastic stroma and profound spatial heterogeneity, yet the multicellular organizational principles governing its tumor microenvironment remain poorly understood. Here, we performed single-cell RNA sequencing (scRNA-seq; n = 9) and spatial transcri...
