1 Tracheal allotransplantation in beagle dogs without immunosuppressants
Yu Liu, MD, Tatsuo Nakamura, MD, Yasuhiko Shimizu, MD, Hiroki Ueda, MD, Makoto Yoshitani, MD, Toshinari Toba, MD, Seijun Fukuda, MD  The Annals of Thoracic Surgery  Volume 72, Issue 4, Pages (October 2001) DOI: /S (01)

2 Fig 1 Bronchoscopic findings in group 1 (left, 7 days after transplantation; right, 314 days after transplantation). No stenosis of the implanted graft was observed. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

3 Fig 2 Macroscopic (A) and histologic findings (B, hematoxylin and eosin staining) in a tracheal graft 314 days after transplantation in group 1. The graft had been incorporated into the host trachea. The outlines of the cartilage rings of the graft are clearly discernible. No absorption of the graft cartilage was observed. The surface of the graft is covered by ciliated columnar epithelium. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

4 Fig 3 Bronchoscopic findings in group 2. Severe stenosis (left, dog 8, 70 days after transplantation) and slight stenosis (right, dog 4, 284 days after transplantation) were observed. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

5 Fig 4 Macroscopic (left, autograft; right, allograft) findings in skin grafts 2 weeks after transplantation. Necrosis of the skin allograft was observed. The Annals of Thoracic Surgery  , DOI: ( /S (01) )
