Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

Scientists in the Brivanlou lab used light-inducible gene expression (yellow circle) and embryo models to demonstrate that, at the start of gastrulation, body-axis formation requires an interplay ...

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

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 ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

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 - ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...

Organoids are made to model human organs and are promising for research and therapy, but there are limitations in their growth and function. A recent study found that placenta-derived IL1 under ...

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, ...

When sperm meets egg, the start of life is not quiet. Under a special microscope, researchers have watched a tiny light show at fertilization. They see a microscopic flash at fertilization, a burst of ...
