Label	Id	Description
dichotomous subdivision of an epithelial terminal unit	GO_0060600	[The process in which an epithelial cord, rod or tube bifurcates at its end.]
positive extrathymic T cell selection	GO_0045067	[The process of sparing extrathymically maturing T cells which react with self-MHC protein complexes with low affinity levels from apoptotic death.]
positive T cell selection	GO_0043368	[The process of sparing immature T cells which react with self-MHC protein complexes with low affinity levels from apoptotic death.]
extrathymic T cell selection	GO_0045062	[The process of T cell selection that occurs in extrathymic locations, often resulting T cells of distinct specificities from those selected in the thymus.]
negative extrathymic T cell selection	GO_0045068	[The process of elimination of extrathymically maturing T cells which react strongly with self-antigens.]
negative T cell selection	GO_0043383	[The process of elimination of immature T cells which react strongly with self-antigens.]
negative thymic T cell selection	GO_0045060	[The process of elimination of immature T cells in the thymus which react strongly with self-antigens.]
thymic T cell selection	GO_0045061	[The process of T cell selection that occurs in the thymus.]
T cell selection	GO_0045058	[The process in which T cells that express T cell receptors that are restricted by self MHC protein complexes and tolerant to self antigens are selected for further maturation.]
T cell differentiation in thymus	GO_0033077	[The process in which a precursor cell type acquires the specialized features of a T cell via a differentiation pathway dependent upon transit through the thymus.]
extrathymic T cell differentiation	GO_0033078	[The process in which a precursor cell type acquires the specialized features of a T cell via a differentiation pathway independent of the thymus.]
epidermis morphogenesis involved in nipple formation	GO_0060660	[The process in which the epidermis of the nipple sheath is uplifted to form an umbrella-like projection.]
placenta development	GO_0001890	[The process whose specific outcome is the progression of the placenta over time, from its formation to the mature structure. The placenta is an organ of metabolic interchange between fetus and mother, partly of embryonic origin and partly of maternal origin.]
ureteric bud morphogenesis	GO_0060675	[The process in which the ureteric bud is generated and organized.]
mesonephric tubule morphogenesis	GO_0072171	[The process in which the anatomical structures of a mesonephric tubule are generated and organized. A mesonephric tubule is an epithelial tube that is part of the mesonephros.]
ureteric bud development	GO_0001657	[The process whose specific outcome is the progression of the ureteric bud over time, from its formation to the mature structure.]
epithelial cell morphogenesis involved in placental branching	GO_0060672	[The change in form (cell shape and size) that occurs when a trophoblast cell elongates to contribute to the branching of the placenta.]
epithelial cell morphogenesis	GO_0003382	[The change in form that occurs when an epithelial cell progresses from its initial formation to its mature state.]
branching involved in labyrinthine layer morphogenesis	GO_0060670	[The process in which the branches of the fetal placental villi are generated and organized. The villous part of the placenta is called the labyrinth layer.]
epithelial cell differentiation involved in embryonic placenta development	GO_0060671	[The process in which a trophoblast cell acquires specialized features of an epithelial cell of the placental labyrinthine layer.]
