Abstract

Help the Aged Muscle function declines with age, as does neurogenesis in certain brain regions. Two teams analyzed the effects of heterochronic parabiosis in mice. Sinha et al. (p. 649 ) found that when an aged mouse shares a circulatory system with a youthful mouse, the aged mouse sees improved muscle function, and Katsimpardi et al. (p. 630 ) observed increased generation of olfactory neurons. In both cases, Growth Differentiation Factor 11 appeared to be one of the key components of the young blood.
