(A) Effect of ADRCs on wound inflammation (histopathologic scoring). Biopsies collected on day 7 and 12 posttreatment were graded by an independent pathologist blinded to wound treatment. (B) Inflammatory infiltrate was graded according to the number of cells within the wound tissue in accordance with a 0–5 point scale as follows: 0 = no infiltrate; 1 = minimal infiltration (1–10 cells/field); 2 = mild infiltration (10–25 cells/field); 3 = moderate infiltration (>25 cells/field); 4 = marked infiltration (heavy infiltrate); and 5 = severe infiltration (packed).
