We have evaluated the potential role of CTAs in early human development.METHODS: Using immunohistochemistry and RT-PCR, we investigated the expression of CTAs in differentiated human embryonic stem cells (hESC) and in late embryos and early fetuses.RESULTS: We found that melanoma antigen A (MAGE-A) family members were expressed during differentiation of hESC to embryoid bodies and in teratomas, and overlapped with expression of the neuroectodermal markers beta-tubulin 3, Pax6 and nestin.
