Could embryonic diapause facilitate conservation of endangered species?

Wauters J , Jewgenow K , Goritz F , Hildebrandt TB

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 c...

Gliding into diapause: early embryo development in roe deer (Capreolus capreolus)

Drews B , Ulbrich SE , Rudolf Vegas A , Jewgenow K , Zahmel J , Roellig K , Ortmann S , Hildebrandt TB , Goeritz F

During mammalian diapause, the embryo is arrested at the blastocyst stage. In diapausing carnivores and marsupials, growth arrest of the blastocyst is coincident with a quiescent corpus luteum (CL). In the roe deer, progesterone is produced throughout diapause and the blastocyst exhibits very slow growth. To date, early roe deer embryos of known age have not been described. Therefore, it is not known at which stage and at what pace the roe deer embryo enters diapause. To colle...
