Drosophila melanogaster is a species of fly ... which have differentiated to perform specialized functions and grow without further cell division.
Schneider 2 cells. Schneider 2 cells, usually abbreviated as S2 cells, are one of the most commonly used Drosophila melanogaster cell lines.S2 cells were derived from a primary culture of late stage (20–24 hours old) Drosophila melanogaster embryos by Dr. Imogene Schneider, [1] likely from a macrophage-like lineage.
Due to its function and its mostly hydrophilic character, Dronc can be located in the apoptosome, the plasma membrane and the nucleus of the cell. Cells containing this protein have been found in the following structures of the Drosophila melanogaster: extended germ band embryo; eye disc; foregut primordium; germline cyst; and gut section. [8]
Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
Germ-band extension is a morphogenic process widely studied in the development of Drosophila melanogaster in which the germ-band, which develops into the segmented trunk of the embryo, approximately doubles in length along the anterior-posterior axis while subsequently narrowing along the dorsal-ventral axis.
Homeobox (Hox) gene expression in Drosophila melanogaster. Drosophila melanogaster is an important model for understanding body plan generation and evolution. The general principles of Hox gene function and logic elucidated in flies will apply to all bilaterian organisms, including humans. Drosophila, like all insects, has eight Hox genes ...
Nuage are the hallmark of Drosophila melanogaster germline cells, which have an electron-dense perinuclear structure and can silence the selfish genetic elements in Drosophila melanogaster. [1] The term 'Nuage' comes from the French word for 'cloud', as they appear as nebulous electron-dense bodies by electron microscopy.
The gene was so named because the Sos protein that it encoded was found to operate downstream of the sevenless gene in Drosophila melanogaster in a Ras/MAP kinase pathway. [1] When sevenless is mutated or otherwise dysfunctional during development of the fly's ultraviolet light -sensitive compound eye , the seventh, central photoreceptor (R7 ...
