Background: To gain insight into the role of satellite cells in skeletal muscle hypertrophy, the effect of radiation on small fiber formation, embryonic myosin heavy chain (embryonic MHC) production, and insulin-like growth factor I (IGF-I) production in overloaded adult rat soleus muscle was examined.

Methods: Adult rat soleus muscle was overloaded by ablation of the synergistic gastrocnemius, plantaris, and flexor digitorum profundus muscles of the right hindlimb. Half of the rats were subjected to gamma irradiation of the right hindlimb prior to ablation in an attempt to prevent satellite cell proliferation.

This study examined the role of longitudinal fiber splitting in enlarged anterior latissimus dorsi (ALD) muscle of adult quail. Muscle hypertrophy was induced using a model of progressive stretch overload (PSO) (5). After 16 and 28 d of PSO, muscle mass in the stretched ALD muscle increased significantly (P < 0.

Skeletal muscle enlargement in adult animals has been ascribed primarily to changes in fiber cross-sectional area (i.e., fiber hypertrophy); however, recent evidence from several laboratories suggests strongly that fiber hyperplasia contributes to muscle mass increases in adult animals and possibly human athletes.
