Figure 3From: A novel oxygen carrier “YQ23” suppresses the liver tumor metastasis by decreasing circulating endothelial progenitor cells and regulatory T cells Comparison of circulating EPCs and Tregs. The populations of circulating EPCs and Tregs were detected by flow cytometry at day 0, 1, 7, 14, 21, 28 after major hepatectomy and I/R injury. (A) The level of circulating EPCs was compared between YQ23 treatment and control groups. (B) The number of circulating Tregs was detected in YQ23 treatment and control groups. (**p < 0.01; N = 3/group).Back to article page
