FGF10 is essential for lung branching morphogenesis and limb outgrowth; Fgf10-/- mice die at birth lacking lungs (pulmonary branching fails after tracheal formation) and have complete fore- and hindlimb truncation. In mutant limb buds, the apical ectodermal ridge (AER) and zone of polarizing activity (ZPA) fail to form. |
