In vivo pluripotency of bovine iPSCs. Teratoma formation at 6–8 weeks after the transplantation of 1F bovine iPSCs into SCID mice was examined. The teratomas were sectioned and stained with hematoxylin and eosin 6–8 weeks after transplantation (upper panels); The sections were stained with antibodies specific for cytokeratin (epithelial cells) or EMA (epithelial cells) (lower panels). Magnification ×400. The red arrow indicates nerve bundles, blood vessels, cytokeratin, and EMA, respectively.
