Expressions of CD133, CD44, and CD82 proteins. (A) Expression of CD133 protein in infiltrating ductal carcinoma. CD133 was expressed as positive in the membrane and cytoplasm of cancer cells (intensity of positivity: strong = 3, percentage of positive cells: >75% = 4, final score = 12, CD133 × 400, G 2). (B) Expression of CD44 protein in IDC. CD44 was expressed as positive in the membrane and cytoplasm of cancer cells (intensity of positivity: strong = 3, percentage of positive cells: >75% = 4, final score = 12, CD44 × 400, G 2). (C) Expression of CD82 protein in IDC. CD82 was expressed as positive in the membrane and cytoplasm of cancer cells (intensity of positivity: moderately = 2, percentage of positive cells: >75% = 4, final score = 8, CD82 × 400, G 2).
