A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in unison ...

Specifically, the researchers wanted to understand how a large group of cells works together to orchestrate a complex, tissue-wide activity like the first heartbeat. “The way most people have thought ...

An illustration of zebrafish heart development, showing the migration of cells in the growing embryo after 17 hours, 1 day and 2 days to form the heart. Most heart cells come from the embryonic ...

In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

An uninjured (left) and injured adult zebrafish heart with neural crest cells labeled magenta. Note the neural crest cells activated around the edge of the injury in preparation for regenerating the ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the ...

Scientists headed by a team at the Chan Zuckerberg Biohub San Francisco (CZ Biohub SF) reported on the development of Zebrahub, a dynamic, state-of-the-art atlas of zebrafish embryonic development.

This rare glimpse into the beating heart of a zebrafish offers a view of how blood flows into and out of its heart. Zebrafish have a heart and a circulatory system similar to that of humans, but with ...
