Supplementary Code for Single-Cell Atlas of Gastric Cancer Progression

A 29.5 KB ZIP file containing supplementary code for a single-cell transcriptomic atlas study. The atlas integrates scRNA-seq data from chronic gastritis, intestinal metaplasia, cancer-adjacent, and tumor tissues. It was authored by Xiulan Li and last updated on April 22, 2026.

Use Cases

• Reproducing cell-cell communication analyses based on the described CD44–ECM axis
• Reconstructing pseudotime trajectories for malignant epithelial differentiation mentioned in the description
• Validating gene regulatory network activity for modules like HNF4/CDX or MYC/TFDP1
• Benchmarking copy number variation inference methods on the described malignant epithelial subgroups

Strengths

• Data is shared under a permissive CC-BY-4.0 license
• Associated with a detailed research study characterizing seven major cell lineages and malignant subgroups

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The 29.5 KB size indicates the dataset is limited to code, not the primary sequencing data
