Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

A new study reveals that age-related autophagy decline blocks embryo development by triggering a lipid-burning crisis.

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Research from Ph.D. candidate Bohan Chen in the lab of Idse Heemskerk of the Department of Cell and Developmental Biology at the University of Michigan Medical School and their colleagues improves ...

"Guinea pigs can become a valuable model for understanding how early disturbances in embryonic development can affect health later in life. Since guinea pig development mirrors that of humans better ...

Scientists have created a comprehensive "atlas" of what early embryonic development looks like in mammals, showcasing how a fertilized egg transforms into a complex organism with a distinctive shape ...

Over half of our genomes consist of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

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 - ...
