B7-H1 Expression Is Required for Human Endometrial Regenerative Cells in the Prevention of Transplant Vasculopathy in Mice

Figure 1

B7-H1 expression on the ERCs is upregulated by IFN-γ in vitro. The fourth generation of ERCs was digested, counted, and adjusted to 1 × 10⁵/ml cell concentration and then stimulated in the presence or absence of 0.05 ng/ml, 0.5 ng/ml, or 5 ng/ml of recombinant human IFN-γ for 72 hours. B7-H1 expression was analyzed by FACS analysis. The intensity of fluorescence-labeled B7-H1 on the surface of ERCs was shown.
