FIGURE 1.

Histological characterization of pectoralis major muscle using Gomori’s Trichrome (TG, A–E), NADH-TR (NADH, F–J) and BODIPY493 (BPY, K–O) staining. Stainings were performed on pectoralis major muscles from a slow-growing genotype (A,F,K) and a fast-growing genotype macroscopically free of defects (B,G,L) or affected by White Striping (C,H,M), Wooden Breast (D,I,N), or both White Striping and Wooden Breast (E,J,O). Bar represents 98 μm (A–E) and 200 μm (F–O). Black arrows indicate regenerative fibers consecutive to segmental fiber necrosis.
