WebIt is the fly Drosophila melanogaster (Figure 21-23), more than any other organism, that has transformed our understanding of how genes govern the patterning of the body. ... The engrailed pattern is shown in a 5-hour embryo (at the extended germ-band stage), a 10-hour embryo, and an adult (whose wings have been removed in this preparation). WebSimultaneous multi-view imaging of Drosophila embryonic development (His2Av-GFPS65T transgenic stock), using the two-photon SiMView framework. The embryo was recorded in 30-second intervals over a period of 2 hours during germ band retraction, using an image acquisition period of 20 seconds per time point.

Germ-band extension is a morphological process widely studied in 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. Germ … See more In order for cells to intercalate between one another the adherens junctions that maintain the integrity of the epithelial tissue must be dynamically remodeled. Time-lapse microscopy has captured this process of cell … See more Researchers suggest that mesoderm invagination provides an anterior-posterior pulling force that contributes to germ-band extension through passive cell shape changes.
