The process in which the epidermis of the nipple sheath is uplifted to form an umbrella-like projection.

The process in which a relatively unspecialized T cell acquires the specialized features of a T-helper 1 (Th1) cell. A Th1 cell is a CD4-positive, alpha-beta T cell that has the phenotype T-bet-positive and produces interferon-gamma.

The process in which a relatively unspecialized thymocyte acquires specialized features of a T-helper cell.

The process in which a relatively unspecialized T cell acquires specialized features of a T-helper 2 (Th2) cell. A Th2 cell is a CD4-positive, alpha-beta T cell that has the phenotype GATA-3-positive and produces interleukin-4.

The process in which a relatively unspecialized T cell acquires specialized features of a cytotoxic T cell.

The process in which the ureteric bud is generated and organized.

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.

The change in form (cell shape and size) that occurs when a trophoblast cell elongates to contribute to the branching of the placenta.

The change in form that occurs when an epithelial cell progresses from its initial formation to its mature state.

Any process that mediates the transfer of information from one cell to another.

The process in which a ureteric bud bifurcates at its end.

The process in which a ureteric bud splits into three units at its end.

The developmental process pertaining to the initial formation of the ureteric bud from the Wolffian duct. This process begins when the bud protrudes from the duct and ends when it is a recognizable bud.

The developmental process pertaining to the initial formation of a mesonephric tubule from unspecified parts. A mesonephric tubule is an epithelial tube that is part of the mesonephros.

The developmental growth in which the ureteric bud grows along its axis beginning with the growth of the primary ureteric bud and ending when the branches of the bud have elongated.

The directed movement of endocytosed material through the cell and its exocytosis from the plasma membrane at the opposite side.

The process that results in the physical movement of a new cis-Golgi stack from the cis-position, nearest the endoplasmic reticulum (ER), to the trans position, farthest from the ER, successively becoming first a medial-Golgi cisterna and then a trans-Golgi cisterna.

The process of sparing immature T cells in the thymus which react with self-MHC protein complexes with low affinity levels from apoptotic death.

A process of protein insertion into the endoplasmic reticulum (ER) membrane in which stop-transfer membrane-anchor sequences become an ER membrane spanning helix.

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.
