As well as using stem cells, regeneration can work by causing differentiated cells that had stopped dividing to ‘go back’ to dividing and multiplying in order to replace the lost tissue. It is not the same as reproduction. A cross-species cytokine protein array detects changes in cytokine/chemokine profiles in axolotl blastema at various time points after amputation relative to baseline expression in uninjured normal limb. During tail regeneration, they all turn on genes in what is called the 'Wnt pathway’ – a process that is required to control stem cells in many organs, such as the brain, hair follicles and blood vessels.
