In conclusion, our results demonstrate that circulating GDF11 levels are reduced in our mouse model of premature aging, which shares most of the symptoms that occur in normal aging. However, GDF11 protein administration is not sufficient to extend longevity in these progeroid mice. Although accelerated-aging mouse models can serve as powerful tools to test and develop anti-aging therapies common to both physiological and pathological aging, the existence of certain differences between the two processes implies that further investigation is still required to determine whether long-term GDF11 administration has a pro-survival effect on normal aged animals. Latest Headlines from Fight Aging! Recent Research on Mechanisms of Limb Regeneration https://www.fightaging.org/archives/2016/08/recent-research-on-mechanisms-of-limb-regeneration/ A number of research groups are engaging in mapping the biochemistry of limb and organ regeneration in species capable of such regrowth, such as salamanders and zebrafish. The hope is that the underlying systems of regeneration are merely inactive in mammals, not missing entirely, and therefore somewhere in all of this lies the basis for a therapy to provoke regrowth of missing tissues in adult humans. Whether or not this is the case is yet to be determined, though some of the evidence is promising: scarless healing of minor wounds present in MRL mice; the same outcome induced via inhibition of Cxcr4; the ability to selecti...
