Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful pregnancy.

The two cells that make up a one-day-old human embryo might look identical at first glance. But a study 1 published today shows that most of the human body forms from only one of those cells — a ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

A 3D uterus embryo implantation simulation chip developed by a Chinese research team has, for the first time, fully ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

The shaping of human embryos begins 4 days after fertilization with a process called compaction, during which the 8 to 16 cells of the embryo come into close contact to form a tighter structure. Four ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are ...

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 ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

When someone says the word embryo, what do you think of? Probably that picture you’ve seen a thousand times on a thousand different news articles: a translucent orb swelling with cytoplasm being ...

Central to many of the bioethical issues of our time is the question, When should society confer moral status on an embryo? When should we call an embryo or a fetus one of us? The fertilized egg ...
