| Research Abstract |
We investigated the effects and possible mechanism of syngeneic bone marrow mononuclear cell (BM-MNC) transplantation on pulmonary arterial hypertension induced by monocrotaline. Monocrotaline-injected mice improved significantly after BM-MNC transplantation compared with those of mice after monocrotaline injection. However, BM-MNCs were not incorporated into the lung at1week after transplantation, and significant vascular endothelial growth factor (VEGF) upregulation and without receptor expression was observed in lung tissue after transplantation. Improvement of pulmonary arterial hypertension was inhibited by simultaneous administration of VEGF receptor-2inhibitor with BM-MNC transplantation. These results indicate that syngeneic BMMNC transplantation improves monocrotaline-induced pulmonary arterial hypertension by favorable pulmonary artery remodeling through VEGF upregulation.
