Figure 3

Histological coronal sections of rat laryngeal specimens stained with H&E, showing the HGF-loaded acellular scaffolds implanted into the right vocal fold wounds and control scaffolds without HGF implanted into the left vocal fold wounds (A) 3 days, (B) 7 days, (C) 30 days, and (D) 90 days after surgery (total magnification = 40 ×). Arrows indicate the implants in the experimental (right) vocal folds and the control (left) vocal folds. Parts (1), (2) and (3) show the interfaces between the control scaffolds and the host tissue 3 days, 7 days and 30 days after surgery, respectively, at a higher magnification (400 ×). Parts (4), (5) and (6) show the interfaces between the HGF-loaded scaffolds and the host tissue 3 days, 7 days and 30 days after surgery, respectively, at a higher magnification (400 ×) (AC = arytenoid cartilage; TA = thyroarytenoid muscle; TC = thyroid cartilage; S = implanted acellular scaffold).
