Identification of hAMSCs and HUVEC. Microscopic view () of hAMSCs at P0 (a). Microscopic view () of HUVECs at P0 (b). Surface marker analysis of freshly isolated hAMSCs by flow cytometry (c–h). The hAMSCs were positive for CD29, CD44, CD73, CD90, and CD105, while negative for CD45, CD34, and HLA-DR. Figure 1(c) acted as negative control for Figures 1(d), 1(e), 1(f), 1(g), and 1(h). The isolated HUVECs expressed CD31 on membrane surface and vWF in cytoplasm (i and j), while they were positive for CD34 and negative for CD45 (m and l). Figure 1(k) acted as negative control for Figures 1(l) and 1(m).
