Zebrafish have a heart and a circulatory system similar to that of humans, but with some important differences. Our hearts have two atria and two ventricles; the atria receive blood from the lungs and ...

Zebrafish protein unlocks dormant genes for heart repair Date: January 2, 2025 Source: Hubrecht Institute Summary: Researchers have successfully repaired damaged mouse hearts using a protein from ...

This is a tissue sample from a zebrafish heart and its surrounding tissues. The golden strands are the muscle cells (1) that make up the ventricle of its heart. The surrounding blue dots are the ...

Abstract: Zebrafish have emerged as a powerful model organism in cardiovascular disease research. Accurately identifying zebrafish blood vessels and evaluating blood flow velocity without injury has a ...

Certain salamanders and zebrafish can regenerate their hearts ... One billion heart-muscle cells—about 25% of muscle cells in ...

Methods Zebrafish embryos (ZFe) were incubated in dexamethasone ... Cardiac function was assessed at 120hpf by ejection fraction, ventricle cardiomyocyte number (DAPI staining), histology and qPCR.
