c-Myb protein expression and localization in skin lesions.

Immunohistochemical stainings of skin lesions of an early (A) and a late (B) stage of mycosis fungoides and an early (C) and a late (D) stage of Sézary syndrome. Hematoxylin-eosin–stained slices from cryo-conserved biopsy material were tested with a c-Myb–specific antibody. Magnifications are 62.5 × (A-C) and 100 × (D). STAT2 (E), STAT5 (F), STAT6 (G), and bcl-2 (H) expression and localization in CTCL skin lesions. Hematoxylin-eosin–stained slices from cryoconserved biopsy material were tested with a STAT5-specific antibody. Magnifications are 100 × (E, G), 62.5 × (F), and 25 × (H).
