Expression Pattern :

Pattern  CEH-18 was detected in the nuclei of the sheath cells of the somatic gonad. In contrast, CEH-18 was not detected in diakinesis stage oocytes, pachytene stage meiotic germ cells, mitotic germ cells, mature sperm, or fertilized oocytes. CEH-18 was present a sheath cell nuclei as early as L4 stage, before the onset of oogenesis. Primary Identifier  Expr1533
