Figure 1. Expression of CT-X antigens in embryonal carcinoma. Examples of MAGE-A (A), NY-ESO-1 (B), GAGE (C), and CT7 (D) expression are shown, illustrating the highly focal nature of CT-X expression in embryonal carcinoma, the only exception being the expression of GAGE in a case of mixed germ cell tumor with embryonal carcinoma component (C).
