Effect of PDGF neutralization on epithelial wound closure and fibroblast invasion. (A) Immunofluorescence staining of the epithelial side of trans-wells (Red: vimentin, Blue: DAPI). (B, C) PDGF-AA neutralization resulted in a significant reduction in NHLFs invasion and significant increase in wound closure. There was no effect of PDGF-AA neutralization on IPF fibroblasts; however, in both A549 only controls and IPF co-cultures it significantly reduced wound closure. No significant changes in either fibroblast recruitment or wound closure were observed with PDGF-BB neutralization in any of the cultures. *P <0.05, **P <0.01 compared to IgG control.
