# Cell Ontology A data package that contains objects representing Cell Types extracted from classes in the Cell Ontology. It also includes transformed object properties between classes into real edges across Cell Type objects. **Sources:** * Cell Ontology * **Doc**: * **Data**: [2024-03-22](https://github.com/obophenotype/cell-ontology/releases/download/v2024-04-05/cl-simple.json) ## Concepts ### Cell Type **Definition:** A material entity of anatomical origin (part of or deriving from an organism) that has as its parts a maximally connected cell compartment surrounded by a plasma membrane. ## Relationships `(CellType) -> is a -> (CellType)` **Definition**: n/a `(CellType) -> develops from -> (CellType)` **Definition**: x develops from y if and only if either (a) x directly develops from y or (b) there exists some z such that x directly develops from z and z develops from y `(CellType) -> has_part -> (CellType)` **Definition**: a core relation that holds between a whole and its part `(CellType) -> develops into -> (CellType)` **Definition**: inverse of develops from `(CellType) -> synapsed to -> (CellType)` **Definition**: Relation between a neuron and an anatomical structure (including cells) that it chemically synapses to. `(CellType) -> synapsed by -> (CellType)` **Definition**: Relation between an anatomical structure (including cells) and a neuron that chemically synapses to it. `(CellType) -> directly develops from -> (CellType)` **Definition**: Candidate definition: x directly\_develops from y if and only if there exists some developmental process (GO:0032502) p such that x and y both participate in p, and x is the output of p and y is the input of p, and a substantial portion of the matter of x comes from y, and the start of x is coincident with or after the end of y. `(CellType) -> has potential to directly develop into -> (CellType)` **Definition**: x has potential to directly develop into y iff x directly develops into y or x is capable of directly developing into y `(CellType) -> derives from -> (CellType)` **Definition**: a relation between two distinct material entities, the new entity and the old entity, in which the new entity begins to exist when the old entity ceases to exist, and the new entity inherits the significant portion of the matter of the old entity `(CellType) -> has synaptic terminal in -> (CellType)` **Definition**: A general relation between a neuron and some structure in which it either chemically synapses to some target or in which it receives (chemical) synaptic input. `(CellType) -> innervates -> (CellType)` **Definition**: Relation between a 'neuron projection bundle' and a region in which one or more of its component neuron projections either synapses to targets or receives synaptic input. T innervates some R Expands\_to: T has\_fasciculating\_neuron\_projection that synapse\_in some R. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.biobox.io/guide/data-packages/external-ontologies/cell-ontology.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
