The time axis shows the status of EBD before and after cell sheet transplantation in subjects 1–3. Blue triangles indicate EBD, red arrows indicate cell sheet transplantation, and a black arrow indicates resection of the stenosis. The distance between triangles and arrows indicates the interval between proceduresBack to article page
