A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults. Scientists ...

A Microscopic Marvel The research, conducted using zebrafish – a tiny species that surprisingly shares many genetic characteristics with humans – used cutting-edge techniques to map the heart ...

A new fully automated in vivo screening system (AISS) has been developed to transform drug evaluation by enabling rapid, precise, and non-invasive multi-organ imaging in zebrafish. Integrating cutting ...

The small size and optical transparence of zebrafish embryos and larvae greatly facilitate modern intravital microscopic phenotyping of these experimentally tractable laboratory animals.

Preclinical drug evaluation, especially for cardiotoxicity, is a critical stage in the drug development process. Traditional methods, often relying on in vitro assays or manual manipulation of ...

This story appears in the September 2017 issue of National Geographic magazine. For a creature that’s less than one and a half inches long, the zebrafish (Danio rerio) looms large in biomedical ...

A study led by Prof. Liu Feng from the Institute of Zoology of the Chinese Academy of Sciences has identified a crucial role ...

The preclinical evaluation of drug-induced cardiotoxicity is an important stage in the drug development process; however, ...

Polystyrene nanoparticles are widely used in packaging, but their effects on organisms are unclear. Very little was known about how they affect blood cell development until now. Red blood cells ...

In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns ...
