Stem Cell Activity

Caption

Human muscle stem cell regenerative activity is depicted in green and red. Stem cell responses were incapacitated when researchers inhibited the activation of key biochemical pathways, making the young muscle behave like old muscle. Encouragingly, old cells were capable of productive regenerative responses similar to their young counterparts when properly triggered by experimental activation of biochemical signals.
