part of develops from adult midgut progenitor cell midgut imaginal island embryonic/larval midgut cell peripheral cell 2014-04-24T18:34:51Z transient pupal midgut cell niche peripheral cell FBbt:00110875 A cell in the larval midgut and early pupal midgut that extends its processes around the midgut imaginal islands (Mathur et al., 2010). These cells are formed at late second larval instar, usually by the first, asymmetric, division of an adult midgut progenitor cell (AMP) (Mathur et al., 2010). There is usually one peripheral cell per imaginal island (Mathur et al., 2010). These cells undergo apoptosis shortly after pupariation (0-2h APF) and do not contribute to the adult midgut (Mathur et al., 2010). Peripheral cells act as a niche for AMPs to keep them undifferentiated until metamorphosis (Mathur et al., 2010). PC These cells can be identified by their expression of a Su(H)GBE reporter, indicating active Notch signaling (Mathur et al., 2010). fly_anatomy.ontology
