  • 1-150 KGF is pro-migratory for lung alveolar epithelial cells (LAEC) seeded on a fibronectin matrix but not on a neutral gelatin matrix.88 135

  • 1-151 IL-6 is equivocal factor of LAEC growth and migration but inhibits TGFα- and EGF-induced LAEC migration on gelatin matrix.88

  • 1-152 IL-2 is equivocal factor of LAEC migration but promoter when cells have been pre-exposed to IFN-γ.88

  • 1-153 Amongst TGFβ isoforms only TGFβ3 is pro-migratory for LAEC.88

  • 1-154 IFN-γ is equivocal factor of LAEC migration but inhibits TGFα- and EGF-induced LAEC migration on gelatin matrix.88
