The GDF11 protein commonly found in the blood of young mice (the same protein that enhanced
neurogenesis in aged mice) and placed in individual older mice was thought to have the same reversal effect on hypertrophy; however, more recent research suggests another molecule besides GDF11 may be at work.

These
mice performed better than their normal counterparts on learning tests well into old
age, and their brains did not exhibit the decline
in neurogenesis typically seen
in aged mice.
The current study reports
neurogenesis (neuron creation) occurred
in the spinal cords of both adult and
aged (over one - year old)
mice of both sexes, although the response was much weaker
in the
aged mice, Dr. Zhang said.
