摘要

Pulmonary arterial hypertension was induced with monocrotaline (MCT) in 60 adult male Wistar rats prior to delivery of lentiviral vector transduced rBMSCs expressing Cav1, eNOS and/or F92A-Cav1. Changes in pulmonary haemodynamics, right ventricular hypertrophy index (RVHI), and serum nitric oxide (NO) were evaluated. Ultrastructure changes in lung tissues were observed by transmission electron microscopy. Expression of Kruppel-like factor 4 (KLF4), p53, P21, eNOS, and alpha-smooth muscle actin were evaluated by real time PCR, western blotting or immunohistochemistry.
