The antigen CD15, also known as 3-fucosyl-N-acetyl-lactosamine (FAL), or Stage Specific Embryonic Antigen (SSEA-1) is a cell membrane and cytoplasmic antigen, that is present in several mammalian tissues. Using immunohistochemistry the monoclonal antibodies 3B9 and B4,3 detected CD15 in whole mount preparations of trophotaeniae of embryos of the matotroph viviparous teleost Xenotoca eiseni. A specific localization is encountered in the ecto- and entodermal portion of the trophotaenial epithelium. A positive reaction in the fibrocytes of the inner mesenchymal core of trophotaeniae is doubtful since a relative high background is present in these cells. CD15 positivity has been observed in all developmental stages studied. The exact role of CD15 is unclear. An involvement in endocytic activity is postulated.

D003532	Cyprinodontiformes	An order of fish with eight families and numerous species of both egg-laying and livebearing fish. Families include Cyprinodontidae (egg-laying KILLIFISHES;), FUNDULIDAEl; (topminnows), Goodeidae (Mexican livebearers), Jenynsiidae (jenynsiids), Poeciliidae (livebearers), Profundulidae (Middle American killifishes), Aplocheilidae, and Rivulidae (rivulines). In the family Poeciliidae, the guppy and molly belong to the genus POECILIA.	Gambusia,Mosquito Fish,Platyfish,Xiphophorus,Fish, Mosquito,Gambusias
D004064	Digestive System	A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).	Ailmentary System,Alimentary System

D004705	Endocytosis	Cellular uptake of extracellular materials within membrane-limited vacuoles or microvesicles. ENDOSOMES play a central role in endocytosis.	Endocytoses
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015214	Antigens, Differentiation, Myelomonocytic	Surface antigens expressed on myeloid cells of the granulocyte-monocyte-histiocyte series during differentiation. Analysis of their reactivity in normal and malignant myelomonocytic cells is useful in identifying and classifying human leukemias and lymphomas.

D015703	Antigens, CD	Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.
