Fig 1 (A) Fresh tracheal epithelium, (B) exfoliated epithelium cryopreserved tracheal allograft (CTA), (C) transplanted CTA in rat showing a macroscopic view of the excised CTA, (D) early period, and (E) late period (hematoxylin and eosin stain; A and B: original magnification × 200).

Fig 2 Histologic examination in the early period of (A and B) control and (C and D) hyperbaric oxygen treatment groups shows no significant histopathologic differences between the groups (hematoxylin and eosin stain; A and C: original magnification ×40; B and D: original magnification ×100).

Fig 3 Histologic examination in the late period. (A and B) Epithelization is visible only in the anastomotic region in the control group. (C and D) Native tracheal epithelium and the allograft epithelium in the hyperbaric oxygen treatment group. A ‘‘competition’’ between epithelial regeneration and fibroblastic proliferation results in (A) tracheal stenosis at control group, (C) and lumen patency in the HBOT group (hematoxylin and eosin stain; A and C: original magnification ×40; B and D: original magnification ×100).
