General Information
Term embryonic/larval crystal cell ID (Ontology) FBbt:00001690 (Fly Anatomy)
Definition Hemocyte of the embryo and larva. A cell that is slightly larger than the plasmatocytes and is distinguished by containing large crystalline inclusions of prophenol oxidase that are not membrane bound (Brehelin, 1982). Crystal cells represent less than 5% of all mature larval hemocytes. They are non-phagocytic cells that facilitate innate immune and wound-healing responses by mediating the process of melanization.[ FlyBase:FBrf0031012 FlyBase:FBrf0035582 FlyBase:FBrf0037631 FlyBase:FBrf0074444 FlyBase:FBrf0085863 FlyBase:FBrf0134542 FlyBase:FBrf0228946 ]
Also Known As "Oe" ; "oenocytoid"
