Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made ...

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 ...

Scientists have identified key molecular events in the earliest stages of human embryo development that could help shed light on why many pregnancies fail. These events occur in the second week of ...

“A central question has been: How do thousands of genes work together in an embryo, and how is their activity linked to the movement of cells?” says first author Yinan Wan. To answer this question, ...

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 ...
