A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Notch on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The process whose specific outcome is the progression of sensory organs over time, from its formation to the mature structure.

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

The process, occurring in the larva, by which the anatomical structures of the salivary gland are generated and organized.

The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.

The process in which the anatomical structures of the imaginal disc-derived wing margin are generated and organized. The wing margin is a strip of cells in the third instar disc at the boundary between the presumptive dorsal and ventral surfaces of the wing blade.

The multiplication or reproduction of glial cells by cell division, resulting in the expansion of their population. Glial cells exist throughout the nervous system, and include Schwann cells, astrocytes, and oligodendrocytes among others.

A discrete cell cycle in the third instar eye imaginal disc after progression of the morphogenetic furrow that contributes to compound eye morphogenesis. It is essential for generation of a sufficient pool of uncommitted cells to develop complete ommatidia.

Any process by which an organism or tissue maintains a population of germ-line stem cells.

The regionalization process that gives rise to the patterns of cell differentiation in the cuticle.

The production of blood cells from the larval lymph gland. The lymph gland consists of three to six bilaterally paired lobes that are attached to the cardioblasts during larval stages, and it degenerates during pupal stages.

Any process that stops, prevents, or reduces the frequency, rate or extent of lamellocyte differentiation. Lamellocytes differentiate massively in the lymph glands after parasitization and are large flat cells devoted to encapsulation of invaders too large to be phagocytosed by plasmatocytes.

Progression of the eye-antennal imaginal disc over time, from its initial formation through to its metamorphosis to form adult structures including the eye, antenna, head capsule and maxillary palps.

Division of an imaginal disc-derived leg into a series of semi-repetitive parts or segments. The Drosophila leg, for example, has nine segments, each separated from the next by a flexible joint.

The process in which a hemocyte precursor cell acquires the characteristics of a crystal cell, a class of cells that contain crystalline inclusions and are involved in the melanization of pathogenic material in the hemolymph.

Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells.

The establishment, maintenance and elaboration of the anterior/posterior axis of the wing disc, a precursor to the wing.

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

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

The external part of the cell wall and/or plasma membrane.

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

The portion of the plasma membrane surrounding an axon; it is a specialized trilaminar random mosaic of protein molecules floating within a fluid matrix of highly mobile phospholipid molecules, 7-8 nm in thickness.

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