In this blog, Vanessa De Mello (Hippo pathway enthusiast and PhD student in the Musculoskeletal group, University of Aberdeen) explores the names behind signalling pathways that control stem cells.
During growth and development the cells that make up our body need to be precisely controlled. If a ‘stop signal’ is constantly given cells will not grow and divide. But if the lights are continually green, too many cells will grow leading to problems like cancer. It is the ‘developmental signalling pathways’ that control this and give our cells instructions on when to grow, divide, or die.
