Figure 2

Purity controls for FACS sorting. Dot-plots in this figure show EB cells labeled with (A) VEGF-R2 antibody at day 2.5, (B) CD41 at day 3.5, and (C) CD144 marker at day 6.5. The plots on the left show total cell populations labeled with the specific cell marker before FACS sorting, while the plots in the middle and right are the purity controls demonstrating the negative and positive cell populations, respectively, after FACS sorting.
