ITGA8 and bronchopulmonary dysplasia: In general, this effect was strongest in the evolving BPD specimens, followed by P.I.G. and was particularly evident in AT2 cells (Fig. 5H), AT1 cells (Fig. 5I), aerocytes (Fig. S5E), capillaries (Fig. S5F), and mesenchymal cell types, whether compared on the basis of label transfer (Fig. S5K–O) or on the basis of shared ITGA8 expression (Fig. 5J).
