A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the basement membrane.

The process whose specific outcome is the progression of the endoderm over time, from its formation to the mature structure. The endoderm is the innermost germ layer that develops into the gastrointestinal tract, the lungs and associated tissues.

A tissue homeostatic process required for the maintenance of epithelial structure.

A tissue homeostatic process required for the maintenance of epithelial structure.

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

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

The process in which the anatomical structures of the viscerocranium are generated and organized during the embryonic phase. The viscerocranium is the part of the skull comprising the facial bones.

The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.

Polarization of the oocyte along the dorsal-ventral axis, by a gene product encoded by somatic cells. An example of this is found in Drosophila melanogaster.

The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade.

Specification of the terminal regions (the two non-segmented ends) of the embryo by the gap genes; exemplified in insects by the actions of huckebein and tailless gene products.

Formation of the amnioserosa, an epithelium that occupies a hole in the embryonic dorsal epidermis. This occurs by the transformation of a narrow strip of cells at the dorsal midline of the blastoderm from columnar to squamous cells, accompanied by a lateral shift.

The process whose specific outcome is the progression of the ectoderm over time, from its formation to the mature structure. In animal embryos, the ectoderm is the outer germ layer of the embryo, formed during gastrulation.

The process whose specific outcome is the progression of the ectoderm over time, from its formation to the mature structure. In animal embryos, the ectoderm is the outer germ layer of the embryo, formed during gastrulation.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

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

The process in which anatomical structures of the veins on an imaginal disc-derived wing are generated and organized.

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

The developmental process in which a skeletal muscle attaches to its target (such as bone or body wall).

A series of molecular signals initiated by the binding of a member of the BMP (bone morphogenetic protein) family to a receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that modulates the frequency, rate or extent of the activity of any BMP receptor signaling pathway.

Any process that activates or increases the frequency, rate or extent of TGF-beta receptor signaling pathway activity.

Any process that stops, prevents, or reduces the frequency, rate or extent of any TGF-beta receptor signaling pathway.

Any process that activates or increases the frequency, rate or extent of BMP signaling pathway activity.

Progression of the ring gland over time, from its formation to a mature structure. The ring gland is a neuroendocrine organ found in higher Dipterans, which is composed of the prothoracic gland, the corpus allatum, and the corpora cardiacum. The ring gland is the site of production and release of ecdysteroids and juvenile hormones.

Any process that stops, prevents, or reduces the frequency, rate or extent of axon regeneration.

The process whose specific outcome is the progression of the posterior Malpighian tubule over time, from its formation to the mature structure. The pair of posterior tubules arise from a ventrolateral region of the embryonic hindgut and project backwards through the body cavity. A Malpighian tubule is a fine, thin-walled excretory tubule in insects which connects with the posterior part of the gut.

A thin layer of dense material found in various animal tissues interposed between the cells and the adjacent connective tissue. It consists of the basal lamina plus an associated layer of reticulin fibers.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

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