Fin regenerative capability abates during aging

Regenerative processes are the reason why wounds can heal and injured tissues can regrow. Some flatworms, salamanders and fishes even have the ability to completely rebuild whole bodily parts. In contrast, the regenerative capability of humans is quite limited and decreases upon aging. Researchers from the Leibniz Institute for Age Research (FLI) in Jena, Germany now found that also in the short-lived killifish Nothobranchius furzeri, the regenerative capability to rebuild its caudal fin heavily lessens in old age.
