To explore the relationships between tumor cells, immune cells, and stroma in pancreatic ductal adenocarcinoma.
Performed imaging mass cytometry on PDAC tissue microarrays of 221 resected tumors.
Generated over 800 multiplexed images focusing on different cell lineages.
Clustered immune and stromal populations to define recurrent microenvironments.
Conducted Lasso-based machine learning to analyze genomic associations.
Identified 76 immune and stromal cell types and 6 cancer cell types with distinct connections to RNA subtypes.
Classical tumor cells were associated with CD105+ CAF microenvironments (odds ratio = 3.7).
ECM-rich microenvironments were found near basal tumor cells (odds ratio = 4.3).
Enrichment of pMLC2+ CAFs was associated with poor-prognosis tumor phenotypes (odds ratio = 4.2).
