Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

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 ...

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 ...

A new King's-led study, published in the Proceedings of the National Academy of Sciences, has found that a single factor (a protein coding gene known as Sox8) can make non-ear cells adopt ear ...

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 ...

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 ...

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 ...

As people age, so do all of our cells, which accumulate damage over time. But why our offspring don’t inherit those changes — effectively aging a child even before birth — has been a mystery. “When ...

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 ...
