Expression of stage-specific embryonic antigen 3 (SSEA3) in adult human skin pre- and postinjury. (A) Brightfield image of human skin preinjury, (B) Immuno-histochemical analysis of SSEA3 expression in normal human skin (preinjury), (C) High-magnification view of SSEA3 expression in the dermis, (D) Brightfield image of human skin postinjury, and (E) Immuno-histochemical analysis of SSEA3 expression in human skin postinjury. SSEA3 expression in green and DAPI staining in white. Scale bars in (B, C) represent 100 μm, and scale bar in (D) represents 50 μm.
