Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating bird embryonic stem cells (ESCs) in the lab. Using a growing medium of egg ...

Surgeons have transplanted dopamine-producing cells derived from human embryonic stem cells directly into the brains of ...
