Abstract:

BACKGROUND: Chronic obstructive pulmonary disease is progressive respiratory disease characterized by airflow limitation.
OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cell transplantation in rats with chronic obstructive pulmonary disease.
METHODS: Sixty healthy male Sprague-Dawley rats were randomly divided into control, model and treatment groups (n=20 per group). Rat models of chronic obstructive pulmonary disease were made in the model and treatment group, while no treatment was done in the control group. After modeling, rats in the treatment group were given tail vein injection of CM-Dil-labeled adipose-derived mesenchymal stem cells, and rats in the model and control groups given the same amount of normal saline. Rat pulmonary ventilation function, inflammatory factor level and pathological changes of the lung were detected at 14 days after cell transplantation.
RESULTS AND CONCLUSION: After modeling, reduced lung function was found in rats with chronic obstructive pulmonary disease, but the cell transplantation significantly improved this reduction (P < 0.05). Compared with the model group, significantly reduced indexes were visible in the treatment group (P < 0.05), including the total number of white blood cells, the number of macrophages and neutrophils, levels of interleukin-8, tumor necrosis factor α and C-reactive protein in the bronchoalveolar lavage fluid as well as serum level of malondialdehyde, while serum superoxide dismutase activity was increased significantly in the treatment group (P < 0.05). In the treatment group, emphysema-like changes were mitigated and CM-Dil-labeled adipose-derived mesenchymal stem cells were capable of homing to the lung tissue of rats with chronic obstructive pulmonary disease and survived. All these findings show that adipose-derived mesenchymal stem cell transplantation can improve lung function of rats with chronic obstructive pulmonary disease, and reduce inflammatory response, which has for certain some therapeutic effects.
