General description

Human embryonal carcinoma (EC) cells are the stem cells of teratocarcinomas, and they are key components of germ cell tumors (GCTs). Embryonal carcinoma, as do all human pluripotent stem cells, expresses TRA-1-60 and TRA-1-81 antigens, and although their molecular identities are unknown, they are commonly used as markers of undifferentiated pluripotent human stem cells.

Specificity

This antibody reacts with TRA-1-81 antigen that is expressed upon the surface of human tetracarcinoma stem cells (EC), human embryonic germ cells (EG) and human embryonic stem cells (ES). No immunoreactivity is seen with murine EC, EG or ES cells. Both the TRA-1-81 and TRA-1-60 monoclonal antibodies (MAB4360) recognize antigens that are associated with a pericellular matrix proteoglycan. TRA-1-60 reacts with a sialidase-sensitive epitope whilst TRA-1-81 reacts with an unknown epitope of the same molecule.

Gamete failure-derived infertility affects millions of people worldwide; for many patients, gamete donation by unrelated donors is the only available treatment. Embryonic stem cells (ESCs) can differentiate in vitro into germ-like cells, but they are genetically unrelated to the patient.
