The development itself is essentially an artificial eggshell, one that allows almost the entire developmental process to ...

The work by Texas-based de-extinction company Colossal Biosciences is part of its plan to ‘de-extinct’ birds, including the ...

Scientists at Colossal Biosciences say they have successfully hatched healthy chicks using a fully artificial egg system.

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, ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...

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 ...
