Abstract:
BACKGROUND:Studies have shown that bone marrow mesenchymal stem cel transplantation can improve disease conditions by reducing inflammation.
OBJECTIVE:To explore the therapeutic efficacy of bone marrow mesenchymal stem cels on chronic asthma rats.
METHODS: A rat model of chronic asthma was established by intraperitonealy injected and aerosolized ovalbumin. After modeling, rats were given 4×105 and 8×105 bone marrow mesenchymal stem celsvia the tail vein, respectively. Thirty days later, the lung tissues were observed pathologicaly using hematoxylin-eosin staining; RT-qPCR and ELISA methods were employed to test the changes in interleukin-10, tumor necrosis factor-α and interferon-γ levels in lung tissue and peripheral blood, respectively.
RESULTS AND CONCLUSION:Rat models of chronic asthma were successfuly established after intraperitoneal injection of ovalbumin combined with aerosolized ovalbumin. After 30 days of cel treatment, the structure of lung tissues were obviously recovered, and the levels of interleukin-10, tumor necrosis factor-α and interferon-γ showed some improvement in lung tissue and peripheral blood, but there were no differences between the two groups. In conclusion, bone marrow mesenchymal stem cels show some potential role in the treatment of chronic asthma.
