Sentences with phrase «imaginal discs»
"Imaginal discs" refers to specialized cells that exist in insects like butterflies and moths. These discs are responsible for the growth and transformation of an insect from its larval stage (caterpillar) to its adult stage (butterfly or moth). They contain all the information needed to create the adult insect's wings, legs, eyes, and other body parts. Essentially, imaginal discs are like blueprints that guide the development of an insect's body during its metamorphosis. Full definition
Figure 5: The regulation of some genes differs between the wing (left) and haltere (right) imaginal discs of Drosophila and is under the control of the Ultrabithorax Hox gene.

Ubx reduces the size of the haltere imaginal disc relative to that of the wing by decreasing the production and mobility of growth - promoting morphogens (for example, Dpp).
Thomas Widmann (Dahmann, MPG)-- «The role of Dpp and Wingless signaling gradients in directing cell shape during Drosophila wing imaginal disc development» (2009)
Dr. Su and her collaborators at University of Colorado, Boulder used ionizing radiation (IR) to induce DNA damage and apoptosis in cells of the wing imaginal disc, the immature form of the fly's wings.
Drosophila has two true wings that develop from imaginal discs of 50,000 cells and two smaller balancing organs called halteres that form from imaginal discs of 10,000 cells.
Wingless signaling and the control of cell shape in Drosophila wing imaginal discs.
My lab uses the wing imaginal disc to dissect the cellular and molecular mechanisms underlying the regulation of tissue growth.
Drosophila imaginal discs, simple epithelial invaginations that grow one thousand fold in mass and cell number, are probably one of the best model systems to analyze at the genetic and molecular level the control of size in a growing epithelium.
