New stem cell research may give the elderly rejuvenated muscles

(Tech Times) – Researchers have taken an old mouse whose heart has thickened and enlarged with age, circulated a newly discovered protein in its blood, and saw that the heart reverted back to a more youthful state. They now believe the same effect can be achieved with elderly humans, using a new process that rejuvenates older muscle stem cell populations so they function like younger cells.
