The Cell Ontology (CL) is a candidate OBO Foundry ontology for the representation of cell types. First described in 2005, the CL integrates cell types from the prokaryotic, fungal, and eukaryotic organisms. As a core component of the OBO Foundry, the CL merges information contained in species-specific anatomical ontologies as well as referencing other OBO Foundry ontologies such as the Protein Ontology (PR) for uniquely expressed biomarkers and the Gene Ontology (GO) for the biological processes a cell type participates in. The CL is under continuous revision to expand representation of cell types and to better integrate with other biomedical ontologies.
We are still setting up this website. In the meantime, please see our information on the OBO Foundry.
