title: Lung development is not necessary for diaphragm development in mice.
abstract: OBJECTIVE
  Congenital diaphragmatic hernia affects approximately 1 in every 2000 live births. The etiology of these diaphragmatic defects is unknown. Using mice with a targeted deletion of fibroblast growth factor 10 (FGF10), which display a complete lack of lung tissue, we have examined the relationship between lung hypoplasia and diaphragmatic development.
  
  
  METHODS
  The diaphragms of FGF10 null mice were examined at 2 embryonic time-points and compared with their heterozygous and wild-type littermates.
  
  
  RESULTS
  FGF10 null mice had phenotypically normal diaphragms when compared with wild-type littermates at both time-points studied.
  
  
  CONCLUSIONS
  Normal diaphragm development appears to occur independent of lung development in mice.
