Figure 6.

Seeding pluripotent cells on nonirradiated (A–D, I–L) and γ-irradiated (E–H, M–P) human foreskin fibroblasts that were treated with 0% (control), 0.01%, 0.05%, and 0.1% SDS. Magnifications: ×20, (A–D, E–H), ×200 (I, O), ×300 (K, L, N, P), ×350 (J, M). Shown are morphological images of seeded human embryonic stem cells by phase contrast microscopy (A–H) and morphological images of seeded induced pluripotent stem cells by scanning electron microscopy (I–P). Abbreviation: SDS, sodium dodecyl sulfate.
