Figure 1 Kinetics of plasma VEGF, ANG-1, TM, and ANG-2 levels after dUCBT. (A-D) Median levels of VEGF (A), ANG-1 (B), TM (C) and ANG-2 (D) from baseline through 12 months post-transplantation are shown. Error bars denote 25th and 75th percentiles.

Figure 2 In vitro angiogenesis assay. (A) Representative images of HUVEC cells cultured with no serum (top row) or with two different concentrations of FCS (second and third row). FCS in the culture medium replaced by human plasma (bottom row).

Figure 3 In vitro angiogenesis assay and correlations with T cell subsets. (A) In vitro angiogenesis assay was performed using 2% plasma from each 1 of 21 dUCBT recipients and angiogenic activity after 18-hour incubation was quantified as described in Methods. Representative images of patients with high (pt1) and low (pt2) plasma angiogenic activity are shown. (B) Total segment length positively correlates with CD4+ (r = .45, P = .04), CD4+CD45R0+ (r = .49, P = .03), and CD4+CD25+ T cells (r = .49, P = .03) after dUCBT. Number of segments and meshes also positively correlated with T cell subsets and TRECs but fell short of statistical significance (data not shown).

Figure 4 Median TM levels in patients with and without cGVHD. Patients who developed GVHD had higher TM levels at baseline (P < .001), at 4 weeks (P = .0045), 8 weeks (P = .01), and 100 days (P = .056) after dUCBT compared with patients without cGVHD.
