Coincidentally, a paper was released in Science in late April that revealed how stem cells function to create an incredible array of colours and patterns in bird…Read more

Managing energy during hibernation: Stem cell metabolome profiling

Author: David Kent, 02/08/13

Previous posts from Angela and Michelle will have alerted readers to the importance of where a stem cell resides in the body. The stem cell niche is a complicated environment and one of the most challenging things for blood stem cell biologists to decipher is how “dormant” stem cells manage their energy in such an…Read more

View from the floor 5: Pushing the boundaries with technology
