Dual PDGFRα- and αSMA-positive cells during alveolar regeneration. A: immunohistochemistry for αSMA (red), PDGFRα (green), and DAPI (blue) DbTg lungs 7 days after completion of RA treatment. B: confocal microscopy after immunohistochemistry for αSMA (red) on triple transgenic RA18 lungs [nuclear green fluorescent protein (GFP) in PDGFRαGFP/WT] demonstrate existence of double-positive PDGFRα and αSMA cells. Expression of dnFGFR during alveolar repair results in no dual positive. Scale bar = 5 μm.
