Article Title: Cellular and Spatial Drivers of Unresolved Injury and Functional Decline in the Human Kidney

doi: 10.1101/2025.09.26.678707

Figure Lengend Snippet: a. Human kidney samples from healthy reference tissues (HRT), as well as disease tissues associated with AKI and CKD, were processed using one or more assays. The strategy included deep single cell and spatial phenotyping, validations with orthogonal technologies and using analytical methods to delineate spatial contexts of recovery and failed repair. This included pathological staining and assessment, 10X Genomics single nucleus / cell RNA-seq and Multiome (RNA + ATAC), 10X Genomics Visium, Slide-seq2, 10X Xenium, Nanostring CosMx and spatial metabolomics. The atlas demonstrates clinical impact and utility to inform on pathogenetic mechanisms, druggable targets, non-invasive markers that predict clinical outcomes from early injury signatures and the underlying regulatory networks that contribute to AKI progression. Abbreviations: Sex (M = male, F = Female, Unk = unknown); Race (W = white, B = Black, O = other); Age range associated with decade-binned age values per participant. Asterix (other reference tissues including Diabetes Mellitus – Resilient (DM-R) biopsies and reference samples with unknown clinical status. b. Pathways predicted for each disease group in each FTU were grouped into 14 whole cell functions, 8 of which are shown. Heatmaps show the sum of the -log10(p-values) of all pathways annotated to the same whole cell function.

Figure Lengend Snippet: a . Slide-seq2 cell types grouped by structure and spatially localized along the cortico-medullary axis. b . Left, a single Slide-seq HRT puck showing renal corpuscle associated cell types. Right, enlarged area of that shown in the left panel for the same cell types and highlighting correct spatial localization of rare MD and REN cells. Tissue pucks are 3mm in diameter. c . Slide-seq2 tissue pucks (halved) associated with HRT (left) and CKD (right), showing enriched mapping for adaptive state epithelial cells (aPT, aTAL, failed repair PT and TAL epithelial cells or frEpi) as well as general fibroblast, lymphoid and myeloid cells in the diseased tissue. d . CosMx cell types grouped by structure and spatially localized to different cortico-medullary fields of view (FOV) for three different diabetic kidney disease (DKD) biopsies. e . Cortical FOV indicated in (d) showing spatial mapping of cell type specific transcripts. Renal corpuscles (RC) are indicated. f . Same FOV as in ( e ) showing protein immunofluorescent staining for epithelial pan cytokeratin (panCK) that highlighted collecting ducts, lymphoid CD45 and T-cell CD3 antibodies. Minimal staining of the latter two is consistent with the low immune cell infiltration found within this FOV. g . Medullary FOV indicated in ( d ) showing spatial mapping of cell type specific transcripts. h . Immunofluorescence staining as in ( f ) and highlighting medullary collecting ducts. i . Enlarged area shown in ( d ) highlighting RC cell types. j . Enlarged area shown in ( d ) highlighting medullary cell types.
