Abstract: | Yolk sac-derived teratomas are composed of various well-differentiated tissues. These tissues must be derived from multipotent cells. To exclude a germ cell origin for these teratomas we used females copulated with males. The embryos generated from such mating comprise 25% sterile embryos, deficient in primordial germ cells, 25% normal embryos (+/+), and 50% heterozygotes (). The results indicate that the genotype of the embryos does not influence the development of teratomas. Displaced yolks sacs belonging to genetically sterile embryos developed into teratomas as frequently as those from heterozygotes and from genetically normal embryos. |
