Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

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

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

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Researchers have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Researchers from the University of Adelaide have discovered ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...
