Glowing and Growing (IMAGE) Rockefeller University Caption Researchers made stem cells fluoresce green (at the base of hair follicles above) by labeling their super-enhancers, regions of the genome bound by gene-amplifying proteins. It appears one such protein, Sox9, leads the activation of super-enhancers that boost genes associated with stem cell plasticity.
