In insects, the oenocytes produce cuticular hydrocarbon compounds. These compounds protect against desiccation and facilitate chemical communication. Here we demonstrate a dissection technique used to isolate the oenocytes from adult Drosophila melanogaster, and illustrate how this preparation can be utilized to study genes involved in hydrocarbon synthesis.

The zebrafish kidney is home to both renal and hematopoietic adult stem/progenitor cells, and represents an outstanding opportunity to study these cell types and their progeny in a vertebrate model organism. Here, we demonstrate a detailed dissection procedure that enables the researcher to identify and surgically remove the adult zebrafish kidney, which can be used for applications such as cell isolation, transplantation, and expression studies of kidney and/or blood cell populations.

The micro-dissected explants technique is a robust and reliable method for isolating proliferative skeletal muscle cells from juvenile, adult or embryonic muscles as a source of skeletal muscle stem cells. Uniquely, these cells have been clonally derived to produce skeletal muscle stem cell lines used for in vivo transplantation.

Drosophila is a powerful model to understand fundamental mechanisms of myogenesis. This protocol for the dissection and preparation of thorax hemi-sections enables microscopy analysis of indirect flight muscle from both pupal and adult stages. This protocol enables confocal imaging of cellular morphology, protein localization, muscle structure, and multiple other aspects of myogenesis.
FAQs
Connective tissues help reveal how muscle fibers are bundled into fascicles and how those bundles continue toward tendons and attachment sites. Separating these layers carefully preserves the spatial relationships needed to interpret muscle organization rather than viewing isolated parts. This structural continuity helps relate the arrangement of tissues to force transmission, contraction, and the direction of movement.
Examining these structures as a connected system shows how muscle organization supports mechanical function. Fascicles represent internal fiber groupings, while tendons and attachment sites indicate where muscular forces are transferred to other structures. Their orientation can therefore be compared with leverage and locomotion, allowing students to connect visible anatomy with the functional consequences of muscle placement.
Keeping associated nerves and blood vessels identifiable adds anatomical context to the muscle itself. Their spatial relationships can be documented alongside fibers, fascicles, tendons, and attachment sites instead of being lost during tissue separation. This broader view supports biological interpretation and provides structures that can be considered when connecting gross anatomy with physiological studies.
Dissection provides a gross anatomical view of mature muscle organization and preserves relationships among visible structures. Microscopic studies examine finer-scale features, whereas physiological studies address contraction and biomechanical studies address movement or leverage. Using these approaches together allows observations from the specimen to be connected with cellular, functional, and mechanical explanations without treating any one scale as complete.
The examination begins by exposing the relevant muscle and then carefully cutting or separating connective tissues to reveal internal organization. Investigators identify muscle fibers, fascicles, tendons, attachment sites, and associated nerves or blood vessels while maintaining their positions where possible. Recording these landmarks creates a basis for comparing muscle structure and relating observations to movement and function.
The procedure can show how muscle position, attachment sites, and internal organization relate to movement. Comparing the orientation of fibers and fascicles with tendon connections helps explain how contraction may contribute to leverage and locomotion. These observations provide anatomical context for later physiological or biomechanical analysis and can help distinguish structural differences among muscles in a mature specimen.
Findings can be used to identify anatomical landmarks, compare muscle organization, and document variation in mature specimens. The observations also provide a foundation for connecting gross anatomy with microscopic structure, muscle physiology, and biomechanics. In biology education and research, this integrated perspective helps explain how visible form relates to contraction, movement, and the organization of skeletal muscle.
