Extraction protocol |
Samples were flash frozen in liquid nitrogen, cryo-sectioned and H&E stained. After sectioning onto the Visium slides, sample processing was performed as described in the Visium 10x Genomics protocol for fresh-frozen tissue samples (15 minutes were used for permealization time) Library preparation was performed as described in the Visium 10x genomics protocol for fresh-frozen tissue samples. After library preparation, samples were pooled and sequenced using a NextSeq 550 (Ilumina, CA, USA). Spatial Transcriptomics Visium 10x genomics

Data processing |
The sequencing outputs for all Visium datasets were preprocessed using SpaceRanger-v1.2.1 and mapped to either the latest human or mouse reference genome and the filtered matrices were converted to Seurat objects in R and used for downstream analyses. Supplementary files format and content: filtered_feature_bc_matrix.tar.gz : Compressed tar archives include Filtered feature-barcode matrices from Space Ranger Supplementary files format and content: spatial.tar.gz : Compressed tar archives include processed output from Space Ranger with spatial information Supplementary files format and content: filtered_feature_bc_matrix.h5 : Filtered feature-barcode matrices in HDF5 format Supplementary files format and content: scMC.merge.all.final.rds : RDS file with all the samples combined Supplementary files format and content: scMC.all.3areas.final.rds : RDS file with selected spots covering the epithelial lining of the IPMN and cancer lesions (“epilesional”); the adjacent PME (‘juxtalesional”), corresponding to two layers of spots (~200 µm) surrounding the lesion; and an additional two layers of spots located further out of the lesions (“perilesional”) Supplementary files format and content: All_RCTD.final.rds : RDS file with RCTD weights
