4. FIGURE 3
(A), Nerve fiber in a red lesion shows high TGFβ1 expression. (B), Nerve fiber in a white lesion shows low TGFβ1 expression (transversal section). (C), Nerve fiber in a black lesion shows no TGFβ1 expression (transversal section). (D), Nerve fiber (arrow) in normal tissue shows no TGFβ1 expression (control group).
