Normal positive staining patterns for OCT4 (Figure S2A in Supplementary Material, brown), NANOG (Figure S2B in Supplementary Material, purple), SOX2 (Figure S2C in Supplementary Material, brown), c-Myc (Figure S2D in Supplementary Material, brown), and KLF4 (Figure S2E in Supplementary Material, purple) were demonstrated on human seminoma, normal skin, breast cancer, and prostate tissues, respectively. Here, MYC is linked to breast cancer.
