General Information
Term adult peritracheal PM cell ID (Ontology) FBbt:00006018 (Fly Anatomy)
Definition Neuropeptide-expressing cell located on the adult trachea. Non-neuropeptide-expressing peritracheal cells, as found in the larva, were not identified in the adult. They are more variably distributed than their larval equivalents and are not always found at branchpoints.[ FlyBase:FBrf0100681 ]
Also Known As"adult peritracheal myomodulin cell"
CommentBased on frequent reporter gene analysis during metamorphosis, these are thought to develop from the larval peritracheal PM cells (O'Brien and Taghert, 1998). Myomodulin-like neuropeptide(s) were detected in these cells before, but not during, eclosion using an antibody against molluscan myomodulin (O'Brien and Taghert, 1998).
