Bone Marrow Mesenchymal Stem Cells Ameliorate Lung Injury th

发布时间：2021-03-14 00:49

　　The anti-inflammatory and antibacterial mechanisms of bone marrow mesenchymal stem cells（MSCs） ameliorating lung injury in chronic obstructive pulmonary disease（COPD） mice induced by cigarette smoke and Haemophilus Parainfluenza（HPi） were studied. The experiment was divided into four groups in vivo: control group, COPD group, COPD+HPi group, and COPD+HPi+MSCs group. The indexes of emphysematous changes, inflammatory reaction and lung injury score, and antibacterial effects were evaluated in all ...
