... enable pattern formation and cell communication. On an organism level, inadequate nutrients or stress can limit germ cell maturation, implantation and maturity through diapause, which slows metabolic activities until embryonic activation under improved environmental conditions. Embryogenesis...

Noriega; Ryusuke Niwa ABSTRACT Female insects can enter reproductive diapause, a state of suspended egg development, to conserve energy under...

...Mark G. Zhang; Paul W. Sternberg ABSTRACT Diapause arrest in animals such as Caenorhabditis elegans is tightly regulated so that animals make appropriate developmental decisions amidst environmental challenges. Fully understanding diapause requires mechanistic insight of both entry and exit from...

...Marilyn B. Renfree; Jane C. Fenelon 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...

..., we have examined the capacity of gp130 mutant embryos to accommodate perturbation of normal developmental progression. Mouse embryos arrest at the late blastocyst stage when implantation is prevented. This process of diapause occurs naturally in lactating females or can be induced experimentally...

...Adam Antebi; Joseph G. Culotti; Edward M. Hedgecock ABSTRACT From egg through adult, C. elegans has six life stages including an option for dauer formation and diapause at larval stage L3 in adverse environments. Somatic cells throughout the organism make consistent choices and advance in unison...
