Fig. 7From: Bone marrow-derived mesenchymal stem cells attenuate pulmonary inflammation and lung damage caused by highly pathogenic avian influenza A/H5N1 virus in BALB/c miceMSCs enhanced regeneration of alveolar epithelial cells. a Immunohistochemical comparison of the expression of Sftpc and Aqp5+ in lung tissue between MSC-treated and mock-treated groups on day 7. There were observed brownish color stains on the cell nucleus under a light microscopy with a X400 magnification, indicating positive expressions of the proteins. b Quantitative comparison of the expressions; the percentage of positive cells was determined by observation of 5 viewing fields for each tissue section. Data shown are means ± SD of 6 mice. ● indicates significant difference (P < 0.05) between two groups. d pi: days post-inoculationBack to article page
