Wounds at 28 days post injury in C57BL/6J mice. Wounds were injected with PBS (A-C), or 1×1011 Genome Copies of AAV2/2 (D-F), AAV2/5 (G-I), AAV2/7 (J-L) or AAV2/8 (M-O). Assessment of transduction efficiencies was assessed in three different wound compartments, the cells in the epidermis (A,D,G,J,M), the cells of the dermis (B, E, H, K, N), or the fascicles of the panniculus carnosus (C, F, I, L, O). Magnification 20x.
