Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

The cell fate determination process in which a germarium-derived cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed. An example of this is found in Drosophila melanogaster.

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The attachment of a somatic follicle cell to another somatic follicle cell or to its substratum, the germline cells. An example of this is found in Drosophila melanogaster.

Polarization of the oocyte along its anterior-posterior axis. An example of this is found in Drosophila melanogaster.

Elongation of the germ band on the ventral side of the embryo, accompanied by a halving in width. The elongation process pushes the posterior midgut invagination closed and compresses the amnioserosa further.

The aggregation, arrangement and bonding together of a set of components to form a synapse. This process ends when the synapse is mature (functional).

The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity.

The process in which the structures of a photoreceptor cell are generated and organized. This process occurs while the initially relatively unspecialized cell is acquiring the specialized features of a photoreceptor cell, a sensory cell that reacts to the presence of light. An example of this is found in Drosophila melanogaster.

Formation and maintenance of a polarized microtubule array originating from a microtubule-organizing center (MTOC) in the oocyte. An example of this is found in Drosophila melanogaster.

Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization of epithelial cells in an embryo.

The delamination process that results in the splitting off of border cells from the anterior epithelium, prior to border cell migration.

The specification and formation of the polarity of a cell along its apical/basal axis.

The cell cycle process in which the directed movement of the mitotic spindle to a specific location in the cell occurs.

Any process in which a protein is transported to, or maintained in, a specific asymmetric distribution, resulting in the formation of daughter cells of different types.

Any process in which a protein is transported to, or maintained in, basal regions of the cell.

Any process in which a protein is transported to, or maintained in, apical regions of the cell.

Assembly of the zonula adherens, a cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.

Assembly of the zonula adherens, a cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.

Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of a neuroblast cell, a progenitor of the central nervous system.

Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of an epithelial cell.

Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of an epithelial cell.

Any cellular process that results in the specification, formation or maintenance of the apicobasal polarity of an epithelial cell.

Any process that stops, prevents, or reduces 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 process resulting in the physical partitioning and separation of a neuroblast into two daughter cells with different developmental potentials.

The process resulting in the physical partitioning and separation of a neuroblast into two daughter cells with different developmental potentials.

The process in which the anatomical structures of branches in the open tracheal system are generated and organized.

The process whose specific outcome is the progression of the Malpighian tubule over time, from its formation to the mature structure. A Malpighian tubule is a fine, thin-walled excretory tubule in insects which leads into the posterior part of the gut.

Any process that modulates the rate, frequency or extent of the establishment of planar polarity, the coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

The developmental growth that results in the elongation of a line that defines polarity or symmetry in an anatomical structure.

Any process in which a protein is transported to, or maintained in, apical regions of the cell.

The attachment of one cell to another cell via adhesion molecules that contributes to the establishment of planar cell polarity.

A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.

A small cell-cell adherens junction assembled during the cellularization stage of insect embyrogenesis; spot adherens junctions later fuse to form the zonula adherens.

A cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

The region of the plasma membrane located at the apical end of the cell.

The region of the plasma membrane located at the apical end of the cell.

The region of the plasma membrane located at the apical end of the cell.

The apical end of the lateral plasma membrane of epithelial cells.

The most apical region of the lateral plasma membrane of an invertebrate epithelial cell. The subapical complex lies above the zonula adherens and the septate junction, and is comparable to the position of the tight junction of vertebrate cells.

A functional unit located near the cell apex at the points of contact between epithelial cells, which in vertebrates is composed of the tight junction, the zonula adherens, and desmosomes and in some invertebrates, such as Drosophila, is composed of the subapical complex (SAC), the zonula adherens and the septate junction. Functions in the regulation of cell polarity, tissue integrity and intercellular adhesion and permeability.

The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.

The region that lies just beneath the plasma membrane on the apical edge of a cell.

The region that lies just beneath the plasma membrane on the apical edge of a cell.
