General Information
Term external sensory organ precursor cell IIc ID (Ontology) FBbt:00100023 (Fly Anatomy)
Definition Second-order precursor cell of multi-innervated external sense organs. It divides to produce only neuronal progeny.[ FlyBase:FBrf0158845 FlyBase:FBrf0167846 ]
Also Known As "pIIc" ; "SOPIIc"
Comment Characterized in developing olfactory sense organs of the antenna (Sen et al., 2003). May not be applicable to other external sense organs. Not clear how this fits with subsequent olfactory sensillum development models, as these cells are not mentioned in Chai et al., 2019 (FBrf0241429) or Endo et al., 2012 (FBrf0217319).
