General Information
Term neuroblast NB5-7 ID (Ontology) FBbt:00111737 (Fly Anatomy)
Definition Neuroblast that is located medial to NB5-4 in the embryo, but does not generate any embryonic progeny (Lacin and Truman, 2016). It proliferates during the larval stage in all thoracic segments to generate postembryonic lineage 20 (Lacin and Truman, 2016). These cells are only found in thoracic segments (Lacin and Truman, 2016).[ FlyBase:FBrf0231327 ]
Also Known As "lineage 20 neuroblast" ; "lineage NB5-7 neuroblast" ; "NB 20" (for all, see Synonyms field below)
Comment Birkholz et al. (2015) suggest that NB5-4 generates postembryonic lineage 20; Lacin and Truman (2016) identify neuroblast NB5-7 and provide lineage tracing data showing that it generates lineage 20. NB5-7 may have evolved as a duplication of NB5-4 (Lacin and Truman, 2016).
