Figure 7: Immunohistochemical Analysis of Inflammatory Cytokines in Vascular Grafts

(A) IL-10. (B) TGF-β. (C) IL-1β. (D) TNF-α. (E) Representative images of cytokine expression within vascular graft cross sections: control (top row) versus bioactive (bottom row). IL-10 stained in green, TGF-β stained in white, IL-1β stained in orange, and TNF-α stained in red. Scale bar represents 1 mm; n = 3 slides (each region of the graft) per animal, with a total of 5 animals per group. Abbreviations as in Figures 1 and 4.
