Preview Dataset: Representative Multi-Institutional Renal Biopsy Patches for Virtual Staining (5 institutions × 3 stains)

This is a preview subset associated with the study "Unified multi-domain virtual staining enables pathologist-concordant renal allograft assessment", which develops and clinically validates virtual staining of renal biopsy whole-slide images across multiple institutions, stains, and scanners. The preview provides 300 de-identified 512×512 image patches representing the diversity of the full dataset (5 tertiary hospitals × 3 stains [H&E, PAS, PM] × 20 patches). It is intended for qualitative reference and reproducibility checks, not for model training. The full dataset is available from the corresponding author on reasonable request, subject to institutional data-governance and IRB policies. License: CC BY-NC 4.0
