Supplementary Materials

This PDF file includes:

  • Fig. S1. FGFR2 and FGFR3 are present in embryonic airway epithelium.
  • Fig. S2. The absence of FGFR3 partially rescues the suppression of branching induced by FGF9.
  • Fig. S3. Loss of FGF9 does not affect epithelial cell death or proliferation.
  • Fig. S4. Overexpression of FGF9 or FGF10 in early-stage lung development does not affect epithelial cell identity.
  • Fig. S5. FGFR3 directs distal epithelial specification and differentiation in pseudoglandular-stage lung.
  • Fig. S6. Overexpression of FGF9 in late-stage lung development does not affect epithelial cell identity.
  • Fig. S7. Inhibition of STAT3 has minimal effects on FGF9 and FGF10 signaling.
