Fig. 13From: Retinoic acid promotes the endogenous repair of lung stem/progenitor cells in combined with simvastatin after acute lung injury: a stereological analysisSchematic view of the role of retinoic acid (RA) and simvastatin (SS) compound in the functional repair of lung stem/progenitor cells in the present study. RA and SS are synergistically involved the remodeling of injured pulmonary tissues. The possible mechanisms refer to the re-balance between regeneration and apoptosis in lung stem/progenitor cells, which is helpful for the pulmonary remodeling/regenerationBack to article page
