Representative flow cytometry plots of viable CEPs, hemangiocytes, and myeloid derived suppressor cells.

<p>An example of the analysis of flow cytometry data obtained from peripheral blood of BALB/c mice is presented. Viable CEPs are determined as (a) positive for VEGFR2 and negative for CD45 as well as (b) positive for CD117 and negative for 7-AAD. Hemangiocytes are determined as (c) positive for CD45 and CXCR4 as well as (d) positive for VEGFR1. Myeloid derived suppressor cells (MDSCs) are determined as positive for (e) both Gr-1 and CD11b.
