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, ...

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

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 ...

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 ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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

"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 ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

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 - ...
