Figure 2. Pluripotency of HK-derived iPS cells verified through spontaneous differentiation in vitro and in vivo. (A) HK-derived iPS clones were analyzed via immunocytochemistry for lineage markers for three germ layers (endoderm, mesoderm and ectoderm). Scale bars indicate 50 μm. (B) Transplant of HK-derived iPS cells into the kidney capsule of SCID-beige mice resulted in teratoma formation. Pictures of harvested kidneys (with or without iPS transplant) are shown. (C) H&E staining demonstrated multiple lineages within the complex architecture of the tumor, including muscle, adipose, immature neuroepithelium and glandular tissues.
