Less frequent are embryonal carcinomas, choriocarcinomas, and yolk-sac (endodermal sinus) tumors in various admixtures and degrees of purity. Teilum [1] first used the term endodermal sinus tumor in 1959 to describe those tumors (whether ovarian, testicular, or extragonadal) that originate in primitive germ cells of extrae...

The differences in the enzyme activity between yolk sac mesoderm and embryo versus yolk sac endoderm can be detected in female concepti by using appropriate crosses of wild-type and G6PD-deficient mice.
