Key molecular signal that shapes regeneration in planarian stem cells discovered

Many living creatures possess exceptional abilities that set them apart from other species. Cheetahs can run up to 60 miles per hour; ants can lift 100 times their body weight; flatworms can regrow amputated body parts. Scientists have spent decades studying the mechanisms that drive such remarkable feats, with the hopes that any secrets they uncover might lead to new perspectives in human biology and new ways to enhance health and ameliorate disease.
