The assembly of a septate junction, an intercellular junction found in invertebrate epithelia that is characterized by a ladder like appearance in electron micrographs and thought to provide structural strength and to provide a barrier to diffusion of solutes through the intercellular space.

Any process that modulates the frequency, rate or extent of endocytosis.

The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. An example of this is found in Drosophila melanogaster.

Polarization of the follicle cells of an insect ovary along the anterior/posterior axis.

Any cellular process that results in the specification, formation or maintenance polarization of a cell's architecture along its apical/basal axis so that the apical and basal regions of the cell have different membrane, extracellular matrix and sub-membrane cellular components.

The behavior of an organism in response to an odor.

Any process that modulates the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.

The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.

Any process in which a protein is transported to, or maintained in, basal 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.

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

The specification and formation of the apicobasal polarity of an epithelial cell.

Any process that stops, prevents, or reduces the frequency, rate or extent of imaginal disc growth.

Any process that modulates the frequency, rate or extent of receptor signaling via JAK-STAT.

The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye.

The process in which a relatively unspecialized cell acquires specialized features of a stem cell. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.

Any process that stops, prevents or reduces the rate or extent of epithelial cell proliferation.

Any process that modulates the physical form or the activity of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell).

Any process that modulates the rate or extent of progression through the cell cycle.

The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells within a field of cells that will exhibit a certain pattern of differentiation. Positional information is established through protein signals that emanate from a localized source within a developmental field resulting in specification of a cell type. Those signals are then interpreted in a cell-autonomous manner resulting in the determination of the cell type.

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.

The multiplication or reproduction of stem cells, resulting in the expansion of a stem cell population. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.

A cell-cell junction that forms a continuous band around each cell in an epithelium; within the septate junction the membranes of adjacent cells maintain a constant distance of approximately 15 nm; found in arthropods.

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 that includes the basal end and sides 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 apical end of the lateral plasma membrane of epithelial cells.

The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.

The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.
