In November, investigators at the Chinese Academy of Sciences reported generating a chimeric monkey by injecting an embryonic stem cell into the morula, which is an extremely early embryo consisting ...

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 ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

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 ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

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 ...

Investigators at the Chinese Academy of Sciences have generated a chimeric monkey by injecting an embryonic stem cell into the morula, which is an extremely early embryo consisting of 16 to 32 cells.
