Figure 3. Severe pathology in intercostal muscle of end-stage DM dogs.

Figure 3

Intercostal muscles were stained with H&E (A and C), and Masson trichrome (B and D), to visualize general morphology of myofibers and presence of fibrotic tissue. (A and B) Myofibers from a control PWC display uniform size and shape with no fibrosis seen between fibers. (C) Myofibers from a grade 4 PWC showing variability in size and shape with hypertrophy (long arrow) and atrophy (short arrow) fibers. (D) End-stage PWC displaying fibrosis (blue stain).
