From: Keratocan Expression Is Increased in the Stroma of Keratoconus Corneas
Immunostaining for decorin. Corneal sections were from a 31-year-old normal human donor (A and B), two patients with keratoconus (C and D, 26-year-old; E, 67-year-old), and a 77-year-old patient with pseudophakic bullous keratopathy (F). Sections were stained with anti-decorin (A, C, E and F) or normal sheep IgG (B and D, negative controls). Positive staining appearing as brown deposits is observed in the corneal stroma (St) as well as the epithelium (*). Note that the staining in the stroma is abnormally increased in diseased corneas (original magnification, ×40).
