Phenotype of triploid embryos

Postimplantation development of CB-induced triploid mouse embryos.

By subjecting A strain eggs at the time of fertilization and polar body extrusion to 5 micrograms/ml cytochalasin B, digynic triploidy was produced in 80% fertilized eggs. Triplonucleate eggs were transplanted to recipients and examined between 9-11th day of pregnancy. Development of triploid mouse embryos up to day 7 is normal and most embryos form early egg cylinder. At day 8 the embryonic pa...

Down-regulation of HLA-G Attenuates Cleavage Rate in Human Triploid Embryos

INTRODUCTION HLA-G is a major histocompatibility complex (MHC), class Ib molecule that is selectively expressed at the fetal-maternal interface. It is thought to play a role in protecting the fetus from the maternal immune response. Interestingly, the preimplantation embryo development (Ped) gene product Qa-2 is also a mouse MHC class Ib protein that affects cleavage and division of preimplanta...

The postimplantation development of spontaneous digynic triploid embryos in LT/Sv strain mice.

When spontaneously ovulating LT/Sv female mice are mated with fertile males, between one third and one half of the zygotes analyzed at the first cleavage mitosis are found to be triploid. This is due to the fact that LT/Sv females ovulate both primary and secondary oocytes, all of which are capable of being fertilized. Fertilization of the former group results in the production of digynic tripl...
