Fig. 6. Expression analyses of Flk1+ cell-derived populations
following induction of Notch1-IC or Numb. Flk1+ cells isolated
from day 2.75 EBs generated from either the Numb or Notch1-IC ES cell line
were cultured as aggregates with VEGF (10 ng/ml) in the presence or absence of
Dox (2 µg/ml). Flk1+ cells prior to culture (0 hours) or
aggregates following 12 hours, 24 hours, and 48 hours of culture were
harvested for qPCR. Average expression normalized to Actb is shown.
Error bars represent the standard errors of mean from three independent
experiments. (A) Sfrp1; (B) Sfrp5; (C)
Wnt5a; (D) Nlk; (E) Dkk1.
