Branching morphogenesis and RAR expression levels of rat hypoplastic lung explant (N) cultures treated with a bombesin or ghrelin antagonist (Bomb Ant or Grl Ant)
A, the number of peripheral airway buds, epithelial perimeter and total area. Results are expressed as the D4/D0 ratio. *P < 0.05. B, RARα, RARβ and RARγ protein expression levels. Representative blots are shown. Protein levels were normalised to β-tubulin, which was used as a loading control. The data are presented as means ± SEM. *P < 0.05; **P < 0.01.
