The protein acts to repair damaged muscle tissue and provide growth factors that improve muscle fiber growth and rejuvenation (1). (drjockers.com)
These results suggest that the additional muscle mass induced by follistatin in Mstn null mice results from inhibition of additional ligands that act predominantly to regulate muscle fiber growth. (journals.plos.org)
Measurements of muscle fiber growth with and without boosting the function of β1 - integrin showed that the protein led to as much as 50 - percent more regeneration in cases of injury in aged mice. (sciencedaily.com)
