Blastocyst 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 کاملovercoming to blastocyst collapse and improvement of blastocyst development in sequential culture media
introduction: this study was started to improve in vitro blastocyst development and avoiding of blastocyst collapsment (no visibie cavity, returning of hatching blastocyst into zona pellucida, and tendency to degeneration). materials and methods: 24hrs one - cell mouse embryos were recovered from positive plug females and cultured in following canditions: experiments 1,2: during first 48hrs nmr...
متن کاملIn vitro porcine blastocyst development in three-dimensional alginate hydrogels.
Appropriate embryonic and fetal development significantly impact pregnancy success and, therefore, the efficiency of swine production. The pre-implantation period of porcine pregnancy is characterized by several developmental hallmarks, which are initiated by the dramatic morphological change that occurs as pig blastocysts elongate from spherical to filamentous blastocysts. Deficiencies in blas...
متن کاملPL-03 Signaling pathways in blastocyst lineage development
to connect cells together is ‘‘adherens junction (AJ)’’, which comprises cadherin receptors, associated proteins termed catenins, and cytoskeletons. The cadherin–catenin complex interacts with actin filaments via a-catenin. Recent analysis identified linkers between a-catenin and F-actin. The presence or absence of such linkers can alter the morphology of cell junctions, epithelial or mesenchym...
متن کاملRegulatory microRNA network identification in bovine blastocyst development.
Mammalian blastocyst formation is characterized by two lineage segregations resulting in the formation of the trophectoderm, the hypoblast, and the epiblast cell lineages. Cell fate determination during these early lineage segregations is associated with changes in the expression of specific transcription factors. In addition to the transcription factor-based control, it has become clear that a...
