Fig. 7From: Predifferentiated amniotic fluid mesenchymal stem cells enhance lung alveolar epithelium regeneration and reverse elastase-induced pulmonary emphysemaTransplantation of LEPLCs attenuated apoptosis in the PPE-induced pulmonary emphysema mouse model. C57BL/6 mice received PBS, AFMSCs, or LEPLCs after 4-week period of PBS, AFMSCs, or LEPLCs treatment following PPE administration. Lung tissues were subjected to immunofluorescence staining to determine the colocalization of apoptotic cells (TUNEL stain; green) and nucleus (DAPI; blue). Scale bar = 100 μmBack to article page
