“…Arrest in non-diapausing blastocysts cannot be profitably induced or maintained artificially in vitro, despite potential indications for decelerated embryonic development, possibly caused by suboptimal culture conditions [27,28]. Thus, such an induced-dormancy/mouse-carrier system might offer new advantages to increase the life span of -for example -in vitro fertilized oocytes that -for whatever reason -cannot be transferred within the right timeframe.…”

During embryonic diapause, the development of the embryo is paused shortly after conception by metabolic or seasonal factors. When conditions become favorable, the embryo will resume development after reactivation by the maternal reproductive system. Inducing this resting state in in vivo or in vitro manipulated embryos may offer invaluable advantages in the long-term storage of embryos, therefore offering a potential worthwhile and novel alternative in assisted reproduction compared to the currently broadly explored cryopreservation.

The blastocyst is a mammalian invention that carries the embryo from cleavage to gastrulation. For such a simple structure, it exhibits remarkable diversity in its mode of formation, morphology, longevity, and intimacy with the uterine endometrium. This review explores this diversity in the light of the evolution of viviparity, comparing the three main groups of mammals: monotremes, marsupials, and eutherians. The principal drivers in blastocyst evolution were loss of yolk coupled with evolution of the placenta. An important outcome of blastocyst development is differentiation of two extraembryonic lineages (trophoblast and hypoblast) that contribute to the placenta. While in many species trophoblast segregation is often coupled with blastocyst formation, in marsupials and at least some Afrotherians, these events do not coincide. Thus, many questions regarding the conservation of molecular mechanisms controlling these events are of great interest but currently unresolved.

The dynamic nature of early embryonic growth is at odds with the phenomenon of mammalian embryonic diapause, because embryos in diapause are in a state of suspended animation of varying duration. The signals that control embryonic diapause differ between species, but in all cases, it acts to synchronise reproduction with external factors to maximise the survival of the offspring. This chapter provides an overview of current understanding of the control of embryonic diapause, with an emphasis on the three species about which most is known, namely, the mouse, the mink and the tammar wallaby.
