General Information
Term terminal tracheal cell ID (Ontology) FBbt:00005053 (Fly Anatomy)
Definition Tracheal tip cell that does not fuse with other trachea, but instead develops into a tracheolar cell - forming secondary trachea and tracheoles. These cells form intracellular seamless tubes that branch extensively.[ FlyBase:FBrf0064787 FlyBase:FBrf0228496 ]
