General Information
Term procrystal cell ID (Ontology) FBbt:00001689 (Fly Anatomy)
Definition An immature crystal cell. These cells measure 8 to 9 micrometers in diameter and can be distinguished from prohemocytes by the lack of cytoplasmic processes and fewer ribosomes, rough endoplasmic reticulum, mitochondria and Golgi bodies (Shrestha and Gateff, 1982). They express lozenge, an early crystal cell marker (Honti et al., 2014).[ FlyBase:FBrf0074444 FlyBase:FBrf0134542 FlyBase:FBrf0223115 FlyBase:FBrf0228946 ]
