      The stains used were hematoxylin and eosin (H&E), Masson's trichrome, and Verhoeff's stain. Sections stained with hematoxylin and eosin have nuclei that were stained blue, cartilage and calcium deposits stained dark blue, cytoplasm and other constituents stained shades of red, and blood stained bright red.

      For overall morphology, sections were stained with hematoxylin and eosin (H&E) to measure mean fiber area.
