| 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).

| 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
