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 ...

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 ...

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
