What this article covers This article describes the datasets available in K-Pro, clarifies how biological data is labelled, and explains what to do when you can't find expected data.
TCGA — The Cancer Genome Atlas: pan-cancer genomic and clinical data
MOSAIC Window — Owkin's proprietary multi-omics dataset. Covers 11 cancer indications, 6 data modalities, and 2,716 patients (clinical, genomics, transcriptomics, spatial transcriptomics, proteomics, histology). Numbers reflect the May 2026 dataset snapshot — see the live Dataset Catalog for current totals. Full dataset catalog available at docs.owkin.com
Scientific literature search via Consensus — AI-powered scientific search engine (consensus.app) integrated into K-Pro. Enables literature-backed hypothesis validation, paper discovery on a gene/disease, and scientific background research.
K-Pro free includes the public MOSAIC and TCGA scope. Some datasets, indications, and modalities (e.g., additional proteomics for Epkin, client-specific cohorts for Servier) are only enabled as add-ons for specific organizations. Your Owkin contact will have shared the exact list of datasets included in your instance during onboarding.
"I can't find blood or adjacent non-tumor tissue data"
The MOSAIC dataset focuses on tumoral biopsies. It does not include blood transcriptomics data. Tissue types that might seem equivalent to "adjacent non-tumor" are labelled by cell type (e.g., epithelial, stromal, immune cells) rather than by tissue origin label.
Example prompt: "Plot the expression of EGFR in malignant and epithelial cells in lung patients from MOSAIC"
"I can't find data for my cancer indication (e.g., lung cancer, PAAD)"
MOSAIC Window covers 11 cancer indications in total. However, in some trial configurations, only a subset of indications is enabled for your instance. To see the full, up-to-date list of indications available in K-Pro, visit docs.owkin.com → Dataset Catalog. If you believe your trial should include an indication that you cannot query, contact your Owkin project manager.
