General Information
Term midgut interstitial cell primordium ID (Ontology) FBbt:00005452 (Fly Anatomy)
Definition Primordium of the midgut interstitial cells. This becomes distinct from the posterior midgut inclusive primordium during stage 11, when its cells delaminate from the tip of the posterior midgut primordium and move postero-ventrally to form a ventral plate of basophilic cells (interstitial cell precursors) wedged between the extending lobes of the posterior midgut primordium. This primordium disappears when its cells intercalate back into the midgut epithelium towards the end of stage 14.[ FlyBase:FBrf0089570 ]
