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 inner ear sensory epithelium of adult zebrafish is a good model system for understanding the mechanisms of hair cell regeneration in adult vertebrates. This protocol demonstrates the fine dissection of the epithelia, through which we can get tissue samples for studying the regenerative events at cellular and subcellular levels.
FAQs
The sequence of controlled incisions through the body wall followed by careful tissue separation creates access to internal organs while keeping the examination organized around anatomical structures. This approach allows researchers to inspect the heart, liver, intestine, and gonads as distinct tissues rather than as an undifferentiated internal mass.
Looking at several organs allows researchers to assess effects across tissues instead of focusing on a single anatomical site. Comparing structures such as the heart, liver, intestine, and gonads can help connect visible anatomical findings with broader changes in physiology, disease processes, development, or toxicology.
Adult zebrafish dissection provides a physical view of organ structure that can be considered alongside molecular and genetic findings. This connection helps researchers relate changes detected at smaller biological scales to particular tissues and organs, supporting a more integrated analysis of how biological processes change throughout the organism.
Appropriate anesthesia and euthanasia precede the examination of internal anatomy. Once those steps are completed, researchers make controlled incisions through the body wall and carefully separate tissues to expose the organs of interest. Following this sequence supports organized anatomical examination and prepares material for subsequent laboratory analysis.
The exposed organs can be examined directly and collected as tissue samples for histology or other investigations described in the study. Histology adds a tissue-focused form of analysis, while collection allows researchers to examine specific organs separately. Together, these uses extend the procedure beyond visual inspection of the whole animal.
The technique is useful when a study needs organ-level information from mature Danio rerio, particularly in investigations of development, physiology, disease, or toxicology. It can reveal how systemic effects appear across tissues and helps connect the zebrafish model's internal anatomy with molecular and genetic research findings.
