In embryonic diapause, the embryo does not immediately implant in the uterus after sexual reproduction has created the zygote, but is maintained in a state of dormancy. Little to no development takes place while the embryo remains ... WebRNA, however, reversed the diapause state in the dKO cells, thus restoring protein synthesis and DNA replication. Similar find-ings of the transcriptome and the reversibil-ity were found when using wild-type cells exposed to a MYC inhibitor that was later removed. Because diapause depends on hormone signaling, it will be interesting to WebThis diapause can last anywhere from a few days to several months, during which the embryo remains in a state of dormancy, just as if it were in deep freeze. The primary advantage of delayed implantation is that it provides the animal with the flexibility to time its reproductive cycle to coincide with optimal environmental conditions. inclusive trauma system nhs scotland
