University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

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 - ...

Every human life begins as a cluster of cells that soon face critical decisions. Within weeks, those cells must choose their fates – some forming the nervous system, others the gut, heart, or muscle.

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 ...

A baby boy born last week to an Ohio couple developed from an embryo that had been frozen for more than 30 years in what is believed to be the longest storage time before a birth. In what's known as ...

Welcome to the world, baby Thaddeus! An Ohio couple says that they have welcomed a baby boy who was born from an embryo that was frozen over 30 years ago. Lindsey Pierce, 35, and her husband Tim ...

A baby boy born last week to an Ohio couple developed from an embryo that had been frozen for more than 30 years in what is believed to be a record length of storage time before a birth. In what’s ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

Research improves upon a popular experimental model of mammal development and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo. Research from Ph.D ...

The research team discovered that glassware used to manipulate and culture fertilized eggs in the fields of assisted reproductive technology (ART), livestock farming, and basic research contains toxic ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...
