General Information
Term larval sheath cell of ovary ID (Ontology) FBbt:00048538 (Fly Anatomy)
Definition Cell found at the anterior end of the developing ovary in the larva. During metamorphosis they subdivide the ovary into 16-20 ovarioles and give rise to the epithelial sheath that surrounds each adult ovariole (Slaidina et al., 2020).[ FlyBase:FBrf0019876 FlyBase:FBrf0021038 FlyBase:FBrf0244767 ]
Also Known As "SH"
Comment Identifiable by expression of stumps and odd (Slaidina et al., 2020).
