Endothelial Progenitor Cell Migration-Enhancing Factors in the Secretome of Placental-Derived Mesenchymal Stem Cells

Figure 3

Effects of soluble factors released from BM-MSCs and PL-MSCs on EPC migration. (a) Diagram of the transwell culture system for an in vitro migration assay. (b) Hematoxylin stained EPCs which migrated to the other side of transwell membrane in response to soluble factors released from BM-MSCs and PL-MSCs. EPCs cultured in transwells containing serum-free medium (SFM) serve as negative controls. (c) Number of EPCs which migrated in response to soluble factors released from BM-MSCs and PL-MSCs. Data were presented as mean ± SEM of three independent experiments. Mann-Whitney test was used to assess the significance of differences between observed data. .
