How does embryonic diapause work
WebThe diapause stage stops the development, for a period of days or months, until the time is right for the developing embryo to awaken, implant to the uterus and resume development into a viable offspring. This enigmatic dormancy-by-design has drawn widespread interest among scientists and science fiction writers alike. WebDiapause is an endocrine-mediated metabolic and developmental arrest induced by changes in abiotic cues that indicate the onset of adverse environmental conditions.10 This arrest …
