Example trichrome stain of injury epicenter. Masson's trichrome stain taken from the epicenter of one representative animal from each injury group; 0.6 mm (A,B) and 0.8 mm (C,D) displacement. Black box in A, C is enlarged below in B, D to illustrate scar thickness. Note that microcysts, particularly in the ventral spinal white matter, are more apparent in the 0.8 than 0.6 mm injury. Scale bar=1 mm (A,C), and 250 μm (B,D). Red staining=cytoplasm, blue staining=collagen (* indicate microcysts). Color image is available online at www.liebertpub.com/neu
