Figure 1From: Conditional deletion of epithelial IKKβ impairs alveolar formation through apoptosis and decreased VEGF expression during early mouse lung morphogenesisGlobal deletion of IKKα disrupts saccular formation. Representative hematoxylin and eosin stained photomicrographs of lung tissue from embryonic stages E13-E18 from wild type littermate controls (A-C; G) and homozygous IKKα -/- knockout progeny (D-F; H).
