Because many zebrafish models of neurological and non-neurological diseases are studied in the adult fish rather than the embryo/larvae, we developed a quantitative lateral line regenerative assay that can be applied to adult zebrafish disease models. The assay involved resolution at the 1) neuromast and 2) individual hair cell levels.

A step-by-step video protocol of apical resection is demonstrated in this study. Apical resection is a recently highlighted surgical approach in mammalian heart regeneration research. This study may promote the application of apical resection as a standard methodology in research into the mechanism underlying heart regeneration.

Use of zebrafish for cardiovascular research is expanding towards research on adult hearts. For these applications, quick and simple isolation of cardiac tissues is key to avoid post-mortem changes and to obtain an adequate number of samples. Here, we describe a fast and reproducible method for dissecting adult zebrafish hearts.

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
Following ventricular injury, cardiomyocytes located near the lesion can re-enter the cell cycle and proliferate. This local response supplies new cardiac muscle rather than treating repair as a purely external process. Studying where these cells respond helps researchers connect injury location with cellular behavior and identify mechanisms that support restoration of cardiac structure and function.
Epicardial and endocardial tissues contribute regulatory signals rather than serving only as structural layers. During the regeneration response, these signals support new vessel formation, help control inflammation, and contribute to scar resolution. Examining these tissue interactions allows researchers to study regeneration as coordinated communication among multiple cardiac cell populations.
Genes, signaling pathways, and cellular interactions represent complementary levels of analysis in zebrafish heart regeneration. Gene studies can identify potential regulators, pathway analysis can place those regulators within biological signaling systems, and cell-interaction studies can reveal how tissues coordinate repair. Together, these approaches help explain why damaged cardiac tissue can recover.
Scar resolution is an important outcome to follow alongside cardiomyocyte proliferation. New muscle formation alone does not capture the full repair response, because vascular support, inflammation control, and removal of scar tissue also shape recovery. This broader view helps distinguish coordinated regeneration from an incomplete response focused on only one cellular event.
Researchers can organize experiments around the sequence that follows ventricular injury: examining cardiomyocyte cell-cycle re-entry and proliferation, assessing signals from epicardial and endocardial tissues, and evaluating vessel formation, inflammation control, and scar resolution. This workflow links cellular events with tissue-level outcomes instead of measuring muscle restoration in isolation.
The model can reveal which genes and signaling pathways are associated with cardiac repair, as well as how different cell types interact during the response. These findings provide mechanistic information rather than only a description of recovery. In biology, that makes zebrafish useful for connecting molecular regulation to tissue repair and restored cardiac function.
Findings from zebrafish heart regeneration can inform research on congenital heart disease, myocardial injury, and regenerative medicine. The value lies in identifying how cardiac tissue responds to damage, how support tissues influence repair, and how scar resolution relates to function. The model therefore connects basic biological mechanisms with medically relevant research goals.
