| Outline of Final Research Achievements |
An artificial human vascular tissue constructed by a cell accumulation method capable of constructing a three-dimensional artificial tissue can be transplanted and expected to be applied to regenerative medicine. In this study, we aimed at transplantation of artificial human lymphatic network tissue (AHLT), fabricated by using human fibroblasts and lymphatic endothelial cells, into nude mice, and verification of its therapeutic effects. As the results, AHLT engrafted in mouse subcutaneous and fascial tissue, and artificial lymphatic vessels had the structures of lymphatic capillaries. In addition, engraftment of small blood vessel-like structures positive for human markers was also observed, and a vascular remodeling including lymphatic vessel-to-vascular conversion was suggested. Furthermore, AHLT transplantation into the lymph node-dissected model gave a result suggesting induction of lymphatic flow regeneration.
