The attachment of a plasma membrane adhesion molecule in one cell to an identical molecule in an adjacent cell.

Growth of the egg chamber between the time it leaves the germarium and the onset of vitellogenesis. During this time both nurse cells and the oocyte undergo developmental changes including nuclear organization and cytoplasmic growth. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of the salivary gland over time, from its formation to the mature structure. Salivary glands include any of the saliva-secreting exocrine glands of the oral cavity.

The process in which the anatomical structures of the foregut are generated and organized.

The process in which the anatomical structures of the hindgut are generated and organized.

The attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

Any cellular process that results in the specification, formation or maintenance of polarized actin-based cytoskeletal structures.

Coordinated organization of groups of cells in the plane of a follicular epithelium, such that they all orient to similar coordinates.

The attachment of one cell to another cell via a cadherin, transmembrane proteins having repeating extracellular calcium ion binding domains.

Any process that activates or increases the frequency, rate or extent of the innate immune response, the organism's first line of defense against infection.

The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.

Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.

Any process that activates or increases the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.

The cell migration process in which a follicle cell migrates as part of an epithelial sheet between the nurse cells and the oocyte. At the end of migration, they cover the anterior of the oocyte.

A process in which a protein is transported to, or maintained in, a location within a cell leading edge.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

The region of the plasma membrane located at the basal end of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.

The area of a motile cell opposite to the direction of movement.

A cell projection supported by an assembly of actin filaments, and which lacks microtubules.
