# What data is available in K-Pro?

{% hint style="info" %}
**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.
{% endhint %}

### Standard datasets included in K-Pro

* **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 vs. add-on data scope

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.

### Why can't I find certain data?

{% hint style="info" %}
**"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"
{% endhint %}

{% hint style="info" %}
**"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.
