Stemness characterization of iPSCs generated by the established protocol. (a) Brightfield image of AP-stained clones. The N3 clone showed the highest number of colonies after 7 days. (b) Colony count of the AP-stained cells in Figure 2(a). Immunocytochemical staining of N1 (c), N2 (d), and N3 (e). N3 showed a slightly higher expression of pluripotency markers than N1 and N2. (; ). (f) Gene expression of pluripotency markers in each clone was confirmed by RT-PCR. Cells were compared to raw PBMCs and fibroblast-derived iPSCs. Scale bars: 200 μm.
