Figure 4. Immunolocalization of ${alpha}$ -SMA expression and uPA production in sections of gingival wounds and healthy gingiva. (A,C,E) ${alpha}$ -SMA expression. (B,D,F) uPA production. (A–D) Acute gingival wounds. (E,F) Healthy gingiva. GT = granulation tissue. HT = healthy tissue. BV = blood vessel. (G) Negative control section. Arrows indicate ${alpha}$ -SMA staining; arrowheads indicate uPA staining. Bar = 50 µm.
