General Information
Term imaginal tracheoblast ID (Ontology) FBbt:00005042 (Fly Anatomy)
Definition Precursor cell of the adult tracheal branches, found in the embryo or larva. Imaginal tracheoblasts originate from the spiracular branches in tracheal metamere 2 to 9, near the junctions with the transverse connectives and from several scattered positions in tracheal metameres 1 and 2.[ FlyBase:FBrf0064787 FlyBase:FBrf0064803 ]
Also Known As"tracheal histoblast"
