Processed single-cell RNA-sequencing datasets and annotation files for the analysis of macrophage heterogeneity in acute pancreatitis

For GSE188819, publicly available count matrices and sample metadata from WT and cerulein-induced AP samples (GSM5690480–GSM5690483) were re-analyzed using a comparable Seurat-based workflow. The repository contains: GSE249349_sample information.xls: sample information compiled from GEO metadata for the samples included in the present analysis. GSE188819_sample information.xls: sample information compiled from GEO metadata for the samples included in the present analysis.

GSE249349_anno.rds: processed and annotated Seurat object generated from the re-analysis of GSE249349. GSE188819_anno.rds: processed and annotated Seurat object generated from the re-analysis of GSE188819. Cell-type annotations were determined based on cluster-specific marker expression identified using Seurat and established macrophage-associated markers.

Macrophage populations were conservatively annotated as M1-like and M2-like states to reflect polarization-associated transcriptional programs rather than discrete macrophage identities. The original sequencing data are publicly available through the Gene Expression Omnibus (GEO) database under accession numbers GSE249349 and GSE188819. This repository provides processed analysis objects and annotation information to facilitate independent evaluation and reuse of the single-cell analyses presented in this study.
