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.

FAQs
Blade profile should match the specimen and the intended task. Straight blades support cutting along a direct path, while curved blades provide a different cutting geometry for separating or exposing tissue. Selecting the appropriate profile helps the operator control the cut and supports accurate preparation without unnecessarily disturbing nearby anatomical structures.
Sharp and blunt tips serve different tissue-handling needs. Sharp tips support precise cutting and tissue isolation, whereas blunt tips can be selected when the task requires a less pointed instrument near biological structures. Matching the tip design to the specimen helps balance access, control, and the preservation of sample integrity during dissection.
The pivot connects the two blades and converts hand pressure into a controlled shearing force. This action allows the blades to meet progressively rather than relying only on crushing pressure, supporting cleaner cuts through tissue. Better control at the joint can help limit tissue damage and preserve spatial relationships for later anatomical observation.
A dissection may use the instrument first to open or expose tissue, then to separate selected regions, and finally to isolate material for examination. These actions connect specimen preparation with anatomical observation. Maintaining controlled cuts throughout the sequence helps retain important spatial relationships and provides a clearer basis for interpreting the specimen.
They are useful when biological work requires tissue isolation, specimen preparation, or exposure of internal structures for observation. Their specialized blade profiles and tips allow the instrument to be selected for the specimen and task. This makes them relevant to practical anatomy work in which accurate cutting and limited tissue damage affect the quality of examination.
Instrument choice can influence how much tissue is removed, separated, or displaced during preparation. A suitable blade shape and tip help produce controlled cuts, while the pivoted design supports shearing rather than uncontrolled force. Preserving sample integrity and spatial relationships makes the resulting specimen more useful for examining how anatomical structures are arranged.
