"These cells co-develop together, just like they would in an actual embryo, and establish that history of being neighbors," Shariati said. "We do not change their genome or expose them to specific ...

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 ...

Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic force microscopy (HS-AFM), they captured the real-time process of ...
