Figure 4From: Conditional deletion of epithelial IKKβ impairs alveolar formation through apoptosis and decreased VEGF expression during early mouse lung morphogenesisEpithelial deletion of IKKβ delays alveolar formation. Representative hematoxylin and eosin stained photomicrographs of lung tissue from embryonic (E12-E17), early postnatal (P0, P7) and young adulthood (P30) stages from IKKβ littermate controls (A-N; top panels) and double transgenic Nkx2.1/IKKβF/F progeny (A-N; bottom panels). (O) Radial alveolar counts at P7 and P30. [4 × magnification in A-L; Data are expressed as Mean ± SEM, * p < 0.05 in O].Back to article page
