Figure 1. FXIIIA⁺ and CD11c⁺ cells are unique dermal populations.

(A) Immunohistochemistry on normal human skin using FXIIIA (left panel) and CD11c (right panel) antibodies (n = 15). FXIIIA⁺ cells were spread throughout the dermis, while CD11c⁺ cells were mainly localized to the superficial dermis. (B) There were similar numbers of CD11c⁺ and FXIIIA⁺ cells per mm in normal dermis. Error bars indicate SEM. (C) FXIIIA and CD11c identified 2 discrete populations. White lines denote dermo-epidermal junction. Scale bars: 100 μm.
