London: Scientists have discovered a chemical that helps tadpoles to re-grow their tail, which could also provide clues to regeneration of human limbs.Researchers led by Enrique Amaya from the University of Manchester have been trying to better understand the regeneration process, in the hope of eventually using this information to find new therapies that will improve the ability of humans to heal and regenerate better.Amaya`s group identified which genes were activated during tail regeneration. Unexpectedly, their earlier study showed that several genes that are involved in metabolism are activated, in particular those that are linked to the production of reactive oxygen species (ROS) - chemically reactive molecules containing oxygen.To examine ROS during tail regeneration, researchers measured the level of hydrogen peroxide (H2O2) - a common reactive oxygen species in cells - using a fluorescent molecule that changes light emission properties in the presence of H2O2.
