Migration of AFSCs is induced by hyperoxia-exposed lung tissues.

<p>(<b>A</b>) AFSCs migration assay using the transwell system. A total of 5x10³ AFSCs were seeded in the inner chamber and minced lung tissues from mice exposed to normoxia (left) or 60 h of hyperoxia (right) were placed in outer chambers. (<b>B</b>) The EGFP-expressing AFSCs that had migrated to the outer chambers were quantified. **p<0.01. Scale bar = 50 µm.
