General Information
Term midgut interstitial cell ID (Ontology) FBbt:00005783 (Fly Anatomy)
Definition Interstitial cell of the midgut. There are 30-40 cells that initially delaminate from the tip of the posterior midgut rudiment during embryonic stages 10 and 11. Later on, they intercalate into the midgut epithelium.[ FlyBase:FBrf0041814 ]
Comment The authors of FBrf0208023 refer to interstitial cells as "absorptive cells" to distinguish them from copper cells, although "absorptive cells" is also a synonym for enterocytes in general.
