General Information
Term imaginal disc epithelial cell ID (Ontology) FBbt:00007108 (Fly Anatomy)
Definition A columnar epithelial cell with distinct apical-basal polarity. The apical surface has microvilli with dense plaques at their tips. A cortical network (ring) of actin filaments underlies the apical surface, extends into the microvilli and is associated with a zonula adherens which encircles each cell. Below this is a broad region of pleated sheet type septate junctions connecting all lateral surfaces to adjacent cells. Plaque-like gap junctions occur mainly interspersed among septate junctions and, at a lower frequency, below them. Small, sparsely distributed hemidesmosomes attach these cells to the underlying basal lamina.[ FlyBase:FBrf0064790 ]
