General Information
Term larval sessile hemocyte ID (Ontology) FBbt:00005496 (Fly Anatomy)
Definition A hemocyte that is not freely circulating, but is attached to the inner surface of the integument or attached to the imaginal discs. Sessile hemocyte islets are segmentally distributed and often located near crystal cells or along the posterior region of the dorsal vessel, concentrated in 2 denser organ-like clusters. These islets contain plasmatocytes, crystal cells and lamellocyte precursors.[ FlyBase:FBrf0134542 FlyBase:FBrf0202807 FlyBase:FBrf0207538 ]
Also Known As "sessile haemocyte"
Comment The 2 denser areas of sessile hemocytes at abdominal segments A and A9 have been referred to as posterior hematopoietic tissue (PHT) (Kurucz et al., 2007).
