From: Differential response of oxidative and glycolytic skeletal muscle fibers to mesterolone
Immunofluorescent identification of satellite cell nuclei (SCN) in cross sections of pectoralis major muscles obtained from control and mesterolone-treated chickens. (A) and (B) represent a section obtained from a control bird. (C) and (D) represent a section obtained from a mesterolone-treated bird. (A) and (C) show all nuclei in blue (DAPI staining) and the basal laminae of muscle fibers in red (anti-laminin staining). (B) and (D) show SCN in green (anti-Pax7 labeling) and the basal laminae in red. As a unique histological feature of the chicken pectoralis, myonuclei are normally found deep within the fiber sarcoplasm12. Scale bar = 30 μm.
