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.

We present a novel method for microgavage of larval zebrafish utilizing standard embryo microinjection and stereomicroscopy equipment. We demonstrate that microgavage is a safe and efficient technique useful for delivering controlled amounts of diverse materials specifically into the larval zebrafish intestinal lumen.

FAQs
The technique exposes internal structures so researchers can examine how organs and tissues are arranged at particular larval stages. Comparing specimens or observations across development can show changes in organization, tissue structure, and organ formation. These anatomical findings help connect visible developmental differences with broader questions about body organization and the relationship between anatomy and function.
Immobilization stabilizes the specimen while fine instruments are used to open the body and separate tissues. This control supports more deliberate handling and helps researchers examine structures without losing the intended anatomical view. It is especially important when the goal is to preserve tissue relationships for microscopy or to document developmental organization accurately.
Separating tissues can make individual structures easier to observe under a microscope, while preservation helps maintain the specimen or selected tissues for examination. Together, these steps improve access to anatomical detail and support comparisons among structures. The resulting preparation can provide direct evidence about tissue arrangement, organ formation, and structural changes during development.
A typical workflow begins by immobilizing the larva, followed by carefully opening the body with fine instruments. Researchers then expose, separate, or preserve tissues according to the purpose of the examination before observing the preparation under a microscope. Each stage contributes to obtaining a clear view of internal anatomy while maintaining useful structural relationships.
Working with larval specimens provides practice in specimen handling, controlled use of fine instruments, and microscopic observation. It also reinforces how anatomical structures can be studied directly rather than inferred from external appearance alone. In teaching biology, the procedure can connect hands-on technique with concepts in tissue structure, comparative anatomy, development, and anatomy-function relationships.
Observations can support investigations of organ formation, tissue structure, developmental changes, and the relationship between anatomy and function. Because the procedure provides direct access to internal organization, it can complement broader developmental and physiological research. Comparative examinations may also help researchers identify similarities or differences in body organization among larval specimens.
