The PDGF pathway regulates angiogenesis of HUVEC
. A. HUVEC were incubated with control (5 % DCC medium) or conditioned media (CM) obtained from either NMF or BJ3Z cells, F-12 K supplement was also used as a positive angiogenesis control; bar 500 μm. Tubule length quantification is shown on the lower panel, n = 3, * and # p < 0,05 by ANOVA followed by Tukey’s post-test versus control. B Imatinib mesylate (IM, black bars) was added to HUVEC; n = 3, *p < 0,05 by Student’s t-test versus control.
