(A) PB iPSCs show a typical morphology of human pluripotent stem cells. (B) A representative karyogram of an iPSC clone. All analyzed PB iPSC clones showed a normal karyotype. (C) PB iPSCs express pluripotency markers OCT4, SOX2, NANOG and SSEA4. Shown are representative confocal images captured using the Zeiss LSM 710 confocal microscope with a 20× objective. (D) PB iPSCs form teratoma in immunodeficient mice. H & E staining of representative teratoma from PB iPSCs shows derivatives of 3 embryonic germ layers. Cartilage (mesoderm); glands (endoderm) and neurotubules (ectoderm). Images were acquired using the Olympus microscope with a 20× objective.
