Immunoreactivity for vimentin (VIM) and desmin (DES) assessed in a slow-growing genotype (A,B) as well as in Pectoralis major muscles of fast-growing chickens exhibiting either macroscopically normal appearance (NORM; A1,B1) or affected by White Striping (WS; A2,B2), Wooden Breast (WB; A3,B3), and Spaghetti Meat (SM; A4,B4) abnormalities. Some fibers were immunoreactive to both VIM and DES (arrows) whereas other were positive to VIM but not to DES (arrowheads). Fibroblasts were positively stained to VIM (asterisks). Bars = 200 μm.
