Is Regeneration a Future Reality? Signaling molecules in Mexican Salamanders may hold the key

From William Hartnell to David Tennant through to Peter Capaldi, the legendary Doctor Who has always had the ability to completely regenerate. The term regeneration is used more generally in Biology to include renewal of cells, tissues and limbs. It is not surprising, therefore, that an exciting new discovery published in Nature by Nacu et al. has shed light on a crucial part of the process involved in limb regeneration(1). Scientists hope that this new insight can be extrapolated for use in mammals, in particular for organ regeneration.
