Blastocyst gene expression correlates with implantation potential.
OBJECTIVE To investigate the role of the blastocyst in implantation failure. This study examined trophectoderm (TE) gene expression relative to pregnancy outcome. DESIGN Retrospective experimental study. SETTING Nonprofit research foundation. ANIMAL(S) Six-week-old BDF1 female mice. INTERVENTION(S) Hatching blastocysts underwent trophectoderm biopsy before single blastocyst transfer (on...
متن کاملEvidence of prostaglandin involvement in blastocyst implantation.
Delayed-implantation mice were used to test for local implantation induction effects of prostaglandins E2 and F2 alpha. Evidence of implantation was gathered by microdissection of implantation sites and by scanning electron microscopy. Indomethacin was tested for the ability to interfere with the mechanisms of estrogen-induced, normal implantation. Both prostaglandins appear to have significant...
متن کاملDiverse Roles of Prostaglandins in Blastocyst Implantation
Prostaglandins (PGs), derivatives of arachidonic acid, play an indispensable role in embryo implantation. PGs have been reported to participate in the increase in vascular permeability, stromal decidualization, blastocyst growth and development, leukocyte recruitment, embryo transport, trophoblast invasion, and extracellular matrix remodeling during implantation. Deranged PGs syntheses and acti...
متن کاملBlastocyst development rate impacts outcome in cryopreserved blastocyst transfer cycles.
OBJECTIVE To assess cycle outcome among day 5 and day 6 cryopreserved frozen-thawed blastocyst embryo transfers (FBET). DESIGN Retrospective cohort study. SETTING Military-based assisted reproduction technology (ART) center. PATIENT(S) One hundred seventy-two nondonor, programmed cryopreserved embryo cycles. INTERVENTION(S) Fully expanded blastocysts on day 5 were cryopreserved on day 5...
متن کاملRegulation of blastocyst formation.
Preimplantation or pre-attachment development encompasses the "free"-living period of mammalian embryogenesis, which directs development of the zygote through to the blastocyst stage. Blastocyst formation is essential for implantation, establishment of pregnancy and is a principal determinant of embryo quality prior to embryo transfer. Cavitation (blastocyst formation) is driven by the expressi...
