Primary AT2 transplants into alternative injury models. Primary AT2 cells were transplanted into acid- (a–c), bleomycin- (d–f), and Sp-injured (g, h) recipients. Transplanted AT2s engraft and expand exclusively as AT2s (a, d, g) or AT1s (b, e, h) in all injury models and never contributed to dysplasia (c, f). Magnified sections and individual channels are derived from dashed boxes to highlight individual cell/marker expression. Scale bars = 100 μm
