Section of skin showing large numbers of dendritic cells (Langerhans cells) in the epidermis. The representation of Langerhans cells in the Cell Ontology. A portion of the Cell Ontology is shown with ovals corresponding to cell types defined in the ontology and arrows corresponding to relations between those cell types.
