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.

A rapid way to conduct immunostaining of zebrafish embryonic heart is described. Compared to the whole mount immunostaining approach, this method dramatically increases the penetration of the antibodies, which allows obtaining high resolution images that reveal cellular/subcellular structures in the heart within a much reduced processing time.

FAQs
Minimizing tissue damage preserves the structures researchers need to interpret. Intact organs and tissues support direct visual examination and microscopic analysis, while poorly handled samples may make anatomical changes harder to distinguish from damage caused by the procedure. Careful isolation therefore improves the connection between observed structure, experimental conditions, mutations, and downstream biological findings.
The procedure allows visible anatomical changes to be examined alongside experimental conditions or genetic mutations. Researchers can compare organ and tissue features to investigate how development, organ function, disease, toxicology, or genetics affect the organism. This anatomical evidence adds a structural perspective to biological studies that may otherwise rely mainly on molecular or functional measurements.
Isolated tissues can support histology, which examines tissue structure, as well as molecular assays that evaluate biological information in sampled material. Researchers may also inspect structures directly or analyze them microscopically before selecting appropriate samples. Combining these approaches helps relate tissue-level observations to broader questions about vertebrate biology and biological effects.
A basic workflow begins by immobilizing the zebrafish, followed by opening the body with fine instruments. Researchers then isolate the organs or other structures of interest while attempting to limit tissue damage. The recovered material can be examined visually or microscopically and may be retained as tissue samples for histology, molecular assays, or related analyses.
The procedure specifically depends on immobilization and the use of fine instruments. Immobilization helps keep the specimen steady, while fine tools allow researchers to open the body and separate structures with greater control. These handling conditions are important because they support accurate anatomical examination and help preserve samples for subsequent microscopic or laboratory analysis.
Researchers use the technique when they need to examine how experimental conditions or mutations affect anatomy, organs, or tissues. Its applications include studies of development, organ function, disease, toxicology, and genetics. Because it also provides material for histology and molecular assays, dissection can connect visible anatomical outcomes with more detailed biological investigations in a vertebrate model.
