General Information
Term adult renal stem cell ID (Ontology) FBbt:00110862 (Fly Anatomy)
Definition Stem cell of the adult Malpighian tubule (Singh et al., 2007). These are small cells occupying a basal position and are only found in the lower tubule and ureter (stem cell zone) (Singh et al., 2007; Wang and Spradling, 2020). They are usually quiescent, but can generate replacement principal cells in response to injury (Wang and Spradling, 2020). Within the stem cell zone, they are more numerous than type I (principal) cells (Wang and Spradling, 2020).[ FlyBase:FBrf0202697 FlyBase:FBrf0245230 ]
Also Known As "adult Malpighian tubule tiny cell" ; "adult RNSC" ; "adult RSC"
Comment Can be identified by expression of escargot (Singh et al., 2007; Wang and Spradling, 2020).
