In brief, increased oxidative stress as a result of redox imbalance during aging leads to increased susceptibility of satellite cells to apoptosis and affects muscle regeneration [6, 8, 29, 30].
This was associated with moderately decreased cell apoptosis, increased numbers of regenerating fibres, and increased satellite cell activation.
Satellite cells are pivotal in muscle regeneration and may be considered as dormant myoblasts (27).
When the researchers injected old mice with GDF11, the population of satellite cells increased, and the number of satellite cells with severe DNA damage fell by a factor of 4.

Through years of perfecting their techniques, a team led by Bursac and graduate student Mark Juhas discovered that preparing better muscle requires two things: well-developed contractile muscle fibers and a pool of muscle stem cells, known as satellite cells.
Human muscle satellite cells can be cultured in vitro in the absence of nerve, and myotubes adequately represent denervated muscle fibres [15].
Moreover, the study on satellite cells [29] and differentiated muscle cells [30] indicated that LLLI promoted SIRT1 deacetylase activity, probably through increased [NAD.sup.+] level or the enhancement of SIRT1 protein expression.
Once the inflammatory reaction has begun it is intensified by satellite cells and necrotic muscle fiber tissue, which stimulate the local release of cytokines (IL-6, IL-1 and cellular growth factors (TNF, FGF, IGF) that amplify the cellular inflammatory response (JARVINEN et al., 2005).
