Fig. 4From: The role of pulmonary mesenchymal cells in airway epithelium regeneration during injury repairDermo1+ stem cells regenerated airway epithelial cells in vitro after LPS treatment. A GFP antibody staining results showed that Dermo1+ cells emerged into the airway epithelium (arrow) at 6 h and 12 h after LPS supplementary in the culture medium. B Ki67 immunostaining results showed that proliferating Dermo1+ stem cells (arrow) were detected in the airway epithelium after 6 h of LPS treatment. C After 6-h treatment of LPS, Dermo1+ cells occurred in the airway epithelium with different migration-like forms (arrow) in frozen sections. Scale bar = 50 μmBack to article page
