Embryonic diapause: a unique stage of development
Abstract
Embryonic diapause is a unique stage of development that occurs in some mammalian species. Diapause serves as an evolutionary reproductive strategy to maximize the survivability of dam and offspring. Although individual mechanisms of control vary among species, the overarching physiology of diapause extends the length of pregnancy to delay parturition until either seasonal, environmental, nutritional, or internal physiologic constraints are optimal for parturition and rearing of young. This review discusses concepts and highlights control mechanisms unique to rodents, mink, and tammar wallabies.
