General Information
Term male germline stem cell ID (Ontology) FBbt:00004929 (Fly Anatomy)
Definition Male germline cell and stem cell from which all other male germline cells develop. Male germline stem cells are part of the germinal proliferation center of the testis. They are arranged around a central hub made up of densely packed hub cells (apical cells), to which they are attached via adherens junctions.[ FlyBase:FBrf0064778 FlyBase:FBrf0190226 ]
Also Known As "male GSC"
