Renal injuries incurred from nephrotoxins, which include drugs ranging from antibiotics to chemotherapeutics, can result in complex disorders whose pathogenesis remains incompletely understood. This protocol demonstrates how zebrafish can be used for disease modeling of these conditions, which can be applied to the identification of renoprotective measures.

In order to understand the molecular mechanisms of the ethanol-induced developmental damage, we have developed a zebrafish model of ethanol exposure and are exploring the physical, cellular, and genetic alterations that occur after ethanol exposure1. We then seek to find potential interventions and rapidly test them in this animal model.

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Zebrafish (Danio rerio) are widely used as an alternative vertebrate model organism in biomedical research. Their genetic similarity to humans, rapid development, and suitability for large-scale studies make them valuable tools...

Source: Li, J., et al. Development of a Larval Zebrafish Infection Model for Clostridioides difficile. J. Vis. Exp. (2020).This video demonstrates the microgavage procedure, where an anesthetized zebrafish larva is immobilized in agarose and orally injected with a pathogenic bacterium using a tracer-guided needle. The non-invasive delivery mimics natural infection, enabling analysis of bacterial replication, toxin release, and intestinal epithelial damage.
FAQs
Transparent zebrafish larvae allow cartilage development to be examined in a living vertebrate rather than only in fixed tissue. Researchers can combine fluorescent staining, histological staining, and imaging to follow craniofacial and skeletal structures as they form. This makes changes in tissue organization and development easier to connect with genetic or disease-related effects.
Genetic manipulation helps researchers investigate how signaling pathways and cell behaviors influence cartilage formation. By examining resulting changes in craniofacial or skeletal tissues, investigators can connect particular biological processes with developmental outcomes. In medicine, this approach supports the study of congenital disorders and skeletal diseases by linking altered gene activity to visible tissue phenotypes.
Because the model examines cartilage within an intact vertebrate, it can connect cellular and signaling events with the development of organized craniofacial and skeletal tissues. Rapid development and accessible embryos also make developmental changes practical to observe. Together, these features help bridge developmental biology and medical research on skeletal formation and disease.
A typical workflow begins with accessible zebrafish embryos or larvae and continues with observation of cartilage development. Researchers may apply fluorescent or histological staining, then use imaging to visualize tissue structure. Genetic manipulation can be incorporated to test signaling pathways or cell behaviors, allowing investigators to compare developmental patterns and disease-associated changes.
The model supports investigation of congenital disorders, skeletal diseases, and tissue regeneration. Researchers can examine how developmental processes produce abnormal cartilage or how tissues respond in regeneration-focused studies. Its craniofacial and skeletal focus provides a way to connect visible structural outcomes with underlying signaling and cell behavior relevant to medicine.
Zebrafish cartilage studies can support therapeutic discovery by allowing potential treatments to be evaluated in vivo, within a living vertebrate system. Rapid development, accessible embryos, and suitability for high-throughput screening help researchers examine many experimental conditions efficiently. Imaging and staining can then provide structural outcomes for assessing effects on cartilage and related skeletal tissues.
