How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

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 ...
