Figure 3From: Therapeutic angiogenesis by transplantation of induced pluripotent stem cell-derived Flk-1 positive cellsTime course RT-CPR in vitro. The expression of Flk-1 was peaked at Day5 from differentiation. Undifferentiated iPS cells markers, Nanog and Oct3/4, were strongly expressed in early phase and started to gradually decrease with differentiation. We also observed the transient expression of c-myc at Day4 and Day5.Back to article page
