Embryo Implantation

open access: yesDevelopmental Biology, 2000
A lesson learned from modern developmental biology is the striking degree of conservation of strategies and molecules used to program developmental events in species as diverse as insects, birds, amphibians, and mammals. Nonetheless, mammals retain distinctions with regard to the strategies used to protect and nourish their offspring during development,

Uterine receptivity, embryo attachment, and embryo invasion: Multistep processes in embryo implantation [PDF]

open access: yesReproductive Medicine and Biology, 2019
AbstractBackgroundRecurrent implantation failure is a critical issue in IVF‐ET treatment. Successful embryo implantation needs appropriate molecular and cellular communications between embryo and uterus. Rodent models have been used intensively to understand these mechanisms.MethodsThe molecular and cellular mechanisms of embryo implantation were ...

Melatonin in maturation media fails to improve oocyte maturation, embryo development rates and DNA damage of bovine embryos Melatonina no meio de maturação não melhorou as taxas de maturação dos ovócitos, de desenvolvimento embrionário e a fragmentação do DNA dos embriões bovinos

open access: yesScientia Agricola, 2010
Melatonin (MEL) acts as a powerful scavenger of free radicals and direct gonadal responses to melatonin have been reported in the literature. Few studies, however, have evaluated the effect of MEL during in vitro maturation (IVM) on bovine embryos.
