When staining Drosophila imaginal discs, often a rough dissection is performed where the discs are exposed but remain attached to the body. Once stained, the discs of interest are isolated and mounted. The example protocol demonstrates a procedure for wing imaginal disc dissection and mounting.

Drosophila melanogaster embryos and larvae are easy to manipulate and develop rapidly by mechanisms that are analogous to other organisms, including mammals. For these reasons, many researchers utilize fly embryos and larvae to answer questions in diverse fields ranging from behavioral to developmental biology. Prior to experimentation, however, the embryos and larvae must first be collected. This video will first demonstrate how "egg-laying cups" are used to collect Drosophila embryos on agar...

FAQs
Saline helps expose, maintain, and inspect larval tissues after the cuticle is opened. Keeping the preparation in saline supports observation of structures such as muscles, the gut, the nervous system, and imaginal discs during microscopy. This makes it possible to examine internal organization while the dissected material remains suitable for direct visual analysis.
The cuticle opening provides physical access to internal tissues that cannot be examined directly through the intact larval exterior. Because the opening must be controlled, researchers can expose selected structures for inspection while limiting disruption to the preparation. This access is essential for viewing tissue arrangement and developmental features at cellular and tissue levels.
Microscopy converts the dissection into a detailed examination of internal organization. It allows researchers to inspect organs and tissues, including the nervous system, muscles, gut, and imaginal discs, at cellular and tissue levels. The resulting observations can reveal differences in development, differentiation, or tissue condition between normal and experimentally altered larvae.
Different internal structures provide complementary information about larval biology. Imaginal discs support examination of developing tissues, while muscles, the gut, and the nervous system reveal organization across other organ systems. Examining these structures in the same general preparation helps connect cellular observations with tissue development and broader physiological responses.
A typical workflow begins by immobilizing the larva, followed by making a controlled opening in its cuticle. Saline is then used as the preparation is exposed and maintained for inspection. Microscopy provides the final examination step, allowing researchers to locate and compare internal structures such as muscles, gut, nervous system, and imaginal discs.
Researchers choose this preparation when they need direct access to developing larval tissues rather than observations limited to the exterior. It is useful for studying organ development, cell differentiation, gene function, and physiological responses. The method also supports comparisons between normal tissues and tissues altered experimentally, linking visible anatomy with biological change.
Dissected larvae make it possible to examine whether experimental changes are associated with visible differences in internal tissues. Researchers can compare structures from normal and experimentally altered larvae, focusing on organs or developing tissues relevant to the study. These comparisons provide cellular- and tissue-level evidence that can inform interpretations of gene function and development.
