  This dataset is released under CC-BY-NC-SA-4.0 strictly for non-commercial
  academic research. Commercial use is not permitted unless explicit written
  permission is granted by the authors.

  ELIGIBILITY. Access is granted only to individuals whose affiliations are
  exclusively academic or public non-profit research institutions. Anyone
  holding any concurrent commercial affiliation — employment, consulting,
  advisory roles, internships, or founding roles at a company or startup — is
  not eligible, regardless of intended use.

  SCOPE. Research performed at, for, funded by, or in collaboration with a
  commercial entity is commercial use and is prohibited. This includes corporate
  R&D, internal evaluation, benchmarking, and proof-of-concept work, even if
  exploratory and never productized. "Research" conducted in a commercial
  setting does not qualify as non-commercial academic research.

  REVIEW. All requests are reviewed manually against these criteria; please
  allow 3-5 business days. By submitting, you agree to share your contact
  information (email and username) with the repository authors. Vague,
  incomplete, or inaccurate submissions will be declined. False or incomplete
  declarations void any access granted and constitute a violation of the license
  terms. For commercial licensing, contact the maintainers.

      Disclose ALL current commercial ties: employment, consulting, advisory
      positions, internships, and founded or co-founded startups. Individuals
      with any concurrent commercial affiliation are not eligible. Failure to
      disclose is grounds for denial and revocation of access.

      Name your institution/lab, the broader research project or area, and

KPMP Xenium virtual spatial transcriptomics

Virtual spatial transcriptomics for the 49 H&E sections of the 10x Xenium kidney biopsies of the Kidney Precision Medicine Project (KPMP), one section per participant: 19,338 genes in each of 1,637,759 cells, predicted with DeepSpot-M Kidney adapted to these sections on their measured Xenium panel genes. Each file also holds the measured Xenium panel of the section.

Model: DeepSpot-M Kidney, finetuned from ratschlab/DeepSpotM · Code: github.com/ratschlab/DeepSpotM · Paper: citation will be added on publication; DeepSpot-M: medRxiv 2026.06.19.26356060.

metadata.csv                                one row per section

Example

CKD biopsy (hMulti panel), per cell: H&E, measured and predicted PODXL (glomeruli; held out from the adaptation) and virtual ALDOB (proximal tubule; not on the panel).

Download

This is a gated dataset: log in first (pip install huggingface_hub).

import pandas as pd
from huggingface_hub import login, snapshot_download, hf_hub_download
login(token="YOUR_HF_TOKEN")

repo = "ratschlab/KPMP_Xenium_virtual_spatial_transcriptomics"

# one enrollment group (leave out allow_patterns for the whole dataset)
snapshot_download(repo, repo_type="dataset", local_dir="KPMP_Xenium_data", allow_patterns="data/CKD/*")

# or select sections in metadata.csv first
meta = pd.read_csv(hf_hub_download(repo, "metadata.csv", repo_type="dataset"))
sel = meta[meta["panel"] == "hKidney_480g"]
snapshot_download(repo, repo_type="dataset", local_dir="KPMP_Xenium_data", allow_patterns=sel.file_path.tolist())

Usage

import numpy as np
import scanpy as sc
import squidpy as sq

adata = sc.read_h5ad("KPMP_Xenium_data/data/CKD/S-2412-005611.h5ad")
adata.X = adata.X.astype(np.float32)
sq.pl.spatial_scatter(adata, color=[None, "PODXL", "ALDOB"], size=0.3, ncols=3)

Data format

X: virtual expression of 19,338 genes per cell, log1p counts per 10,000 (log1p CP10k) on the scale of the Xenium panel the decoder was adapted to, stored as float16 (cast to float32 before analysis).
layers['ground_truth']: measured Xenium expression (log1p counts per 10,000 over the panel genes), sparse, zero outside the panel genes.
obs: one row per cell: cell_id (Xenium cell id), sample_id (KPMP specimen id), participant_id, enrollment, panel, imaging_site, centroid in full-resolution H&E pixels (x_pixel, y_pixel) and in Xenium micrometres (x_um, y_um).
var: HGNC gene symbol, ensembl_ids, hgnc_id, in_panel_hKidney / in_panel_hMulti (measured on that Xenium panel; SLC9A3R1 and TMEM173 under their current symbols NHERF1 and STING1) and heldout (74 panel genes left out of the adaptation in every section).
obsm['spatial'] and uns['spatial']: cell centroids and an H&E overview image, as scanpy and squidpy expect.
uns['he2st']: section and processing metadata, with the adaptation and the H&E-to-Xenium registration (he_px_to_xenium_um, 3 × 3, and its QC distance).
metadata.csv: one row per section: file path, participant, specimen, enrollment group, panel, imaging site, number of cells (n_cells), in_kpmp_visium_training (participant in the KPMP Visium training data of DeepSpot-M Kidney), in_kpmp_he_atlas (participant in the KPMP virtual spatial transcriptomics atlas) and the KPMP download links of the Xenium bundle, the H&E image and the metadata file.
