Figure 3From: Transplantation of endothelial progenitor cells in treating rats with IgA nephropathy Identification of EPCs. The cells were collected and analyzed by flow cytometer for CD34, CD133 and FLK-1. The population of positive cells was indicated as percentage number in figures (A). The cells were also fixed and dual stained with DiL-acLDL (red)/ FITC-UEA-1 (green). Merged images showed that most cells were dual-postive. Dual-postive cells were defined as EPCs (B).Back to article page
