In utero treatment with ASCFTR causes structural changes in the lung of adult rats. Lung sections from 3 months old rats were stained with hematoxylin and eosin and viewed by light microscopy. Frequent areas showing airway thickening and multilayered epithelia (filled arrows) were observed in the ASCFTR rat lungs (B and D), while the control lungs showed normal architecture (A and C). Some alveolar areas (open arrows) with cellular infiltration were also observed in the ASCFTR rats. Original magnification, A and B ×100; C and D ×200
