| Outline of Final Research Achievements |
Objectives: To investigate the effects of human umbilical cord blood-derived mononuclear cell (hUCB-MNC) transplantation on pulmonary hypertension (PH) induced by monocrotaline (MCT) in immunodeficient mice and their distribution. Methods: Fresh hUCB-MNCs harvested from a human donor after her delivery were injected intravenously into those PH mice (BALB/c Slc-nu/nu) 4 weeks after MCT induction. To reveal the incorporation into the lung, CMTMR-labeled hUCB-MNCs were observed in the lung. DiR-labeled hUCB-MNCs were detected in the lung and other organs by bioimaging. Results: PH was significantly improved 4 weeks after hUCB-MNC transplantation. CMTMR-positive hUCB-MNCs were observed in the lung 3 hours after transplantation. Bioluminescence signals were detected more strongly in the lung than in other organs for 24 hours after transplantation. Conclusions: The results indicate that hUCB-MNCs are incorporated into the lung early after hUCB-MNC transplantation and improve MCT-induced PH.
