Selective expression of paternal human major histocompatibility antigens on the surface of hydatidiform mole cells.
The typing of human major histocompatibility antigens (HLA) of two cases of invasive hydatidiform mole showed that the fibroblast-like cells as well as trophoblasts from the mole selectively expressed paternal HLA haplotype specificity but not maternal HLA on the surface. This result was completely in agreement with the notion of androgenetic origin of hydatidiform mole from the aspects of HLA specificity. Immunological implication of this finding and development of chorionic tumor were discussed in the light of fetomaternal relationship and host immune surveillance against the tumor.
