WormMine: ExpressionPattern Expr13979

• Pattern: DDO-3::mCherry was localized in the excretory pore cell, head tip cells, and hypodermal cells. On the other hand, DDO-3::mCherry was not localized in proximal gonadal sheath cells at any point during development, suggesting that DDO-3 is secreted from these cells in a SP-dependent manner. Interestingly, in the adult stage, DDO-3::mCherry was localized on the surface of the oocyte, which is surrounded by gonadal sheath cells, suggesting that DDO-3 produced in and secreted from proximal gonadal sheath cells is transferred to the oocyte surface. Furthermore, DDO-3::mCherry was also localized in the eggshell within the adult uterus, as well as in the uterine space, and it remained localized in the eggshell until hatching. In hermaphrodites, in addition to the excretory pore cell, head tip cells, hypodermal cells, oocyte surface, uterine space, and eggshell, DDO-3::mCherry was also present in coelomocytes from the late embryonic stage, and accumulated in vesicle-like structures at least from the adult stage.
