Figure 5From: Platelet-derived growth factor alpha and beta receptors have overlapping functional activities towards fibroblastsThe effect of collagen gel contraction of dermal fibroblasts after treatment with PDGFRα and PDGFRβ neutralising antibodies. Dermal fibroblasts were treated with neutralising antibodies to anti-PDGFRα, anti-PDGFRβ or blank for 1 h at room temperature and were added to a collagen gel. The gels were then grown in media containing either PDGF-AA or PDGF-BB. After 24 h the gels were weighed to assess contraction. Error bars are standard error of the mean. Two-sample T-test statistical analysis was performed compared to compared gel weights compared to the 0% FCS control p = 0.004 PDGF-AA, p = 0.032 PDGF-BB, p = 0.82 anti-PDGFR-α., p = 0.62 anti-PDGFR-α.+ PDGF-AA, p = 0.03 anti-PDGFR-α.+ PDGF-BB, p = 0.77 anti-PDGFR-β, p = 0.035 anti-PDGFR-β + PDGF-AA, p = 0.0007 anti-PDGFR-β + PDGF-BB. *p > 0.05.Back to article page
