RÉSUMÉ
<p><b>OBJECTIVE</b>To compare the angiogenesis behaviors of vascular endothelial growth factor (VEGF) and Chinese medicine Xuefu Zhuyu Decoction (, XZD) treatments.</p><p><b>METHODS</b>Human microvascular endothelial cells (HMEC-1) were treated with various concentrations of either XZD-containing serum (XZD-CS) or VEGF for 24, 48, and 72 h, respectively. Cell viability, proliferation, migration, adhesion, and in vitro tube formation assays were used to assess their angiogenic effects.</p><p><b>RESULTS</b>VEGF promoted all cellular phases involved in angiogenesis including cell viability, proliferation, migration, adhesion, and tube formation (<0.05 or <0.01). Unlike the continuous promotion effects of VEGF at the above stages, XZD inhibited cell viability and proliferation (<0.05 or <0.01) and only promoted tube formation in the early phase of angiogenesis (<0.01).</p><p><b>CONCLUSIONS</b>These two medications promote different angiogenesis behaviors, which might be an important reason for their distinct therapeutic profile in clinical usage.</p>
