General Information
Term primary lobe of embryonic/larval lymph gland ID (Ontology) FBbt:00001669 (Fly Anatomy)
Definition Anterior-most and largest of the 3-6 lobe pairs of the third instar embryonic/larval lymph gland. These lobes are bulbous. Three distinct zones are identified: the medullary zone in the center, the cortical zone in the periphery and the posterior signaling center. At the late third instar the posterior signaling center functions as a stem-cell niche, the medullary zone contains quiescent prohemocytes, and the cortical zone the proliferating hemocytes (plasmatocytes) and procrystal and crystal cells.[ FlyBase:FBrf0074444 FlyBase:FBrf0187467 FlyBase:FBrf0208762 FlyBase:FBrf0228946 ]
Also Known As "anterior lymph gland pair" ; "primary lymph gland lobe"
