Endothelial phenotype in 2D/3D cultured hADSCs after 21 days. Uptake of Ac-LDL/UEA-1 in the 3D induced hADSCs (a), 3D noninduced hADSCs (e), 2D induced hADSCs (i), and HUEVC (m) at 21 days in vitro examined by laser confocal microscopy (scale bars: 50 μm). Immunofluorescence stainings of endothelial markers of vWF ((b), (f), (j), and (n)), VEGFR2 ((c), (g), (k), and (o)), and CD31 ((d), (h), (l), and (p)) in the 3D induced hADSCs, 3D noninduced hADSCs, 2D induced hADSCs, and HUVEC (scale bars: 100 μm).
