Immunofluorescence characterization and teratogenicity of NPC. NPCs immunostained for detection of intracellular neural stem cell specific antigens, including nestin (A), vimentin (B), and beta-tubulin (C), and pluripotency factors Oct3/4 (E) and Nanog (F). Bright field image showing cluster of neural stem cells formed in vitro (D). Inset boxes depict staining with corresponding isotype antibodies. Dissociated NPCs were embedded in Matrigel and injected s.c in NOD/SCID mice. Teratomas failed to form in any of the 4 mice injected with NPCs (G) and tumor tissues was also not detected after subcutaneous dissection (H).
