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 ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

It's one of life's most defining moments - that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage ...

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 ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...
