Figure 3.

(A) Introduction of CDy1-stained mPSC with or without light exposure through subcutaneous injection; images of teratoma developed from CDy1-stained mPSC with (0/10: zero out of ten mice) and without (10/10: ten out of ten mice) light exposure are shown. (B) Image of typical three germ layers from the teratoma stained with hematoxylin and eosin containing gut for endoderm, adipose tissue and cartilage for mesoderm, and keratin pearl for ectoderm (scale bar; 100 μm). (C) Size distribution of 10 teratomas measured in CDy1 treated mice with and without light exposed.
