Regenerating Salivary Glands in the Microenvironment of Induced Pluripotent Stem Cells

Figure 1

Histological analysis of teratoma formation after transplantation of GFP-iPS cells. Images of sections of teratomas formed after transplantation of GFP-iPS cells into salivary glands of SCID mice. A teratoma formed from transplantation of 5.0 × 10⁵ GFP-iPS cells. H&E stained sections of a teratoma showing derivatives of all three germ layers, including gut-like epithelium tissues ((a) endoderm), adipose tissues and muscles ((b) mesoderm), and neural tissues and keratin-containing epidermal tissues ((c) ectoderm). Scale bars, 50 µm.
