Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

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 ...

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 ...

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 ...

"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 ...

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 - ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...
