Figure 1From: Id1 enhances human ovarian cancer endothelial progenitor cell angiogenesis via PI3K/Akt and NF-κB/MMP-2 signaling pathwaysPhenotypic characterization of EPCs from human peripheral blood. (A) After 1 week in culture, EPCs were stained with DIL-labeled ac-LDL, FITC-conjugated Ulex europaeus lectin. vWF, VEGFR2 and CD31 analysis were assessed by immunofluorescence (× 20). (B) Detection of cell markers on EPCs by flow cytometry, from left to right: isotype-negative control, the percentage of VEGFR2-positive cells, isotypenegative control and the percentage of CD34-positive cells.Back to article page
