Explore the Cancer Dependency Map
Welcome to the DepMap Portal!
The goal of the Dependency Map (DepMap) portal is to empower the research community to make discoveries related to cancer vulnerabilities by providing open access to key cancer dependencies analytical and visualization tools.Use this portal to:
DISCOVER genetic and pharmacological dependencies

PRIORITIZE tumor contexts and predictive biomarkers
Explore the relationship between MTAP expression and PRMT5 dependency

EXPLORE over 2000 cancer models

BROWSE and download the latest datasets

Visit the DepMap Community Forum to ask questions, report issues and share your suggestions.
Call for Cancer Cell Models
We wouldn’t be able to build DepMap without the help of the many collaborators and partners who have already shared their cell lines and organoids.If you are interested in identifying cancer vulnerabilities in your favorite models, please consider sharing them and allowing us to generate data which will be available to the entire community.
Announcements
We've corrected a mistake where "DepMap Public 20Q4 v2" on the downloads page was incorrectly downloading files from the "DepMap Public 20Q4" release. The download links have been corrected.
We identified issues with several files in the “DepMap Public 20Q4” dataset and have loaded a new release labeled "DepMap Public 20Q4 v2", which addresses those issues, into the portal. See this post on the forum for more details..
New data in 20Q4 We are happy to report that we have released CRISPR data for 19 lines this quarter to bring our total number of cell lines with Avana CRISPR data to 808.
Target validation protocols Our most commonly used target validation protocols are now public at protocols.io - an open repository of protocols.
Whole Genome Sequencing (WGS) in DepMap We have begun generating WGS rather than WES for cell lines. Although only CN and exonic mutations are reported for this release, we are working to add additional data from WGS in future releases.
Removing Cell Lines from all Omics datasets We are removing ACH-001189, ACH-002303, ACH-002315, ACH-002341 from the all omics datasets since they are duplicate entries.
Y Chromosome Missing - CN dataset Y chromosome was missing from copy number calls in some cell lines. This issue has been resolved in the new release by using a new panel of normal samples. For some cell lines, minor changes have occurred to overall copy number calls in all chromosomes. Lines which significantly deviated in their autosomal CNV from previous release have not been incorporated and are being assessed further for future release.
Removal of cell lines - expression and fusion datasets We are removing 10 lines that did not pass QC in the expression and fusion datasets. Please see details in the README files in the Downloads page.
New features and data updated quarterly
This portal enables analysis of data generated at the Broad Institute jointly with data generated elsewhere including:
- Omics data from the Cancer Cell Line Encyclopedia (CCLE)
- Gene dependency data from Broad’s Project Achilles
- Small-molecule sensitivity data from Broad’s PRISM Repurposing
- Novartis’ Project DRIVE
- Sanger’s Project Score
- Sanger’s GDSC
- Broad’s CTD2
- Quantitative proteomics from the Gygi lab
As part of our commitment to Open Science, we make all the Broad Institute data generated by the DepMap Project rapidly available to the public under the permissive CC BY 4.0 license on a quarterly basis and prepublication.
Because this portal also hosts data not generated by the Broad Institute DepMap Project, please be sure to review the data policy for each dataset prior to use.
