Lipid droplets in mammalian eggs are utilized during embryonic diapause. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance Lipid droplets (LDs) are stored in the embryo throughout the preimplantation development. Yet, the role of LDs in the embryo remains unknown. Embryonic diapause (ED) is a temporary arrest of an embryo when it waits for the uterine receptivity signal to implant.

A role for Msx genes in mammalian embryonic diapause. [PDF]
Biosci Proc, 2020 Mammalian embryonic diapause is a reproductive phenomenon defined by the reversible arrest in blastocyst development and metabolic activity within the uterus which synchronously becomes quiescent to implantation. This natural strategy, evident in over 130 species across eight orders, can temporally uncouple conception from delivery until conditions are

Molecular Regulation of Paused Pluripotency in Early Mammalian Embryos and Stem Cells
Frontiers in Cell and Developmental Biology, 2021 The energetically costly mammalian investment in gestation and lactation requires plentiful nutritional sources and thus links the environmental conditions to reproductive success.

Veterinary Journal of Mehmet Akif Ersoy University, 2021 Embryonic diapause or temporary cessation of embryonic development is a common phenomenon in the plant and animal species. Embryonic diapause is a temporary cessation of the development of embryogenesis in the blastocyst stage and is a reproductive strategy characterized by delayed implantation in the uterus.

Review: Embryonic diapause in the European roe deer – slowed, but not stopped
Animal, 2023 Embryonic diapause in mammals describes a transient reduction of proliferation and developmental progression occurring at the blastocyst stage. It was first described in the European roe deer (Capreolus capreolus) in the 19th century, and later found to ...

Circadian Clock Genes Regulate Temperature-Dependent Diapause Induction in Silkworm Bombyx mori
Frontiers in Physiology, 2022 The bivoltine strain of the domestic silkworm, Bombyx mori, exhibits a facultative diapause phenotype that is determined by maternal environmental conditions during embryonic and larval development.

A preliminary approach to embryonic development of Austrolebias wolterstorffi, an endangered neotropical annual fish species [PDF]
Brazilian Journal of Biology, 2023 Annual fish live exclusively in temporary wetlands and are among the shortest-lived vertebrates in the world. These fish persist in these habitats due to drought-resistant eggs, that which, through diapauses are able to detect stimuli from the ...

The enigma of embryonic diapause [PDF]
Development, 2017 Embryonic diapause – a period of embryonic suspension at the blastocyst stage – is a fascinating phenomenon that occurs in over 130 species of mammals, ranging from bears and badgers to mice and marsupials. It might even occur in humans. During diapause, there is minimal cell division and greatly reduced metabolism, and development is put on hold.

Embryonic diapause and its regulation [PDF]
Reproduction, 2004 Embryonic diapause, a condition of temporary suspension of development of the mammalian embryo, occurs due to suppression of cell proliferation at the blastocyst stage. It is an evolutionary strategy to ensure the survival of neonates. Obligate diapause occurs in every gestation of some species, while facultative diapause ensues in others, associated ...
