The multiplication or reproduction of epithelial cells of the submandibular salivary gland, resulting in the expansion of a cell population and the shaping of the gland.

The developmental process pertaining to the initial formation of a submandibular salivary gland. This process begins with a thickening of the epithelium next to the tongue and ends when a bud linked to the oral surface is formed.

The process in which the solid core of salivary epithelium gives rise to the hollow tube of the gland.

The formation of a lumen by hollowing out a solid rod or cord.

The differential growth of the salivary branches along their axis, resulting in the growth of a branch.

Any process that modulates the rate, frequency, or extent of salivary gland branching as a result of the transfer of information from the extracellular matrix to the epithelium of the salivary gland.

Any process that modulates the rate, frequency, or extent of branching involved in salivary gland morphogenesis as a result of signals being generated by the mesenchyme and received and interpreted by the salivary gland epithelium.

The process in which a salivary epithelial cord bifurcates at its end.

The process in which an epithelial cord, rod or tube bifurcates at its end.

The process in which the embryonic placenta is generated and organized.

The process in which a relatively unspecialized T cell acquires specialized features of a regulatory T cell. Regulatory T cells control or suppress immune responses through a variety of mechanisms and subsets include the CD4+CD25+ cell type as well as certain CD8+ cell types.

The process of sparing extrathymically maturing T cells which react with self-MHC protein complexes with low affinity levels from apoptotic death.

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

The process of T cell selection that occurs in extrathymic locations, often resulting T cells of distinct specificities from those selected in the thymus.

The process of elimination of extrathymically maturing T cells which react strongly with self-antigens.

The process of elimination of immature T cells which react strongly with self-antigens.

Any process that modulates the frequency, rate or extent of viral genome replication.

The process of elimination of immature T cells in the thymus which react strongly with self-antigens.

The process of T cell selection that occurs in the thymus.

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.
