Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

Researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form. Can a single ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Studying embryogenesis is key to unraveling the mysteries of early life. luismmolina/iStock via Getty Images Plus Embryonic development, also known as embryogenesis, is a cornerstone in understanding ...

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

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 ...
