AVR-48 improves lung morphology. (A) Representative H&E stained lung paraffin sections showing histological changes after AVR-48 treatment. (B) Chord length (which measures the average free distance in the air spaces) is increased in the BPD group and normalizes after AVR-48 treatment. (C) The alveolar septal thickness is decreased and (D) the radial alveolar count (which measures the number of alveoli) is also improved after AVR-48 treatment. *** p < 0.001, n = 3–8; RA: room air; BPD: bronchopulmonary dysplasia. Scale bar 100 µm.
