How to make a blastocyst [PDF]
Biochemistry and Cell Biology, 1992 Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the ...

Journal of Human Reproductive Sciences, 2013 Objectives: The literature regarding clinical outcomes following day 5/6 vitrified warmed blastocysts transfer has been conflicting. We decided to evaluate and compare the clinical outcomes following vitrified warmed day 5/6 blastocyst transfer using a ...

Frontiers in Endocrinology, 2021 It is well known that the transfer of embryos at the blastocyst stage is superior to the transfer of embryos at the cleavage stage in many respects. However, the rate of blastocyst formation remains low in clinical practice.

Reproductive Biology and Endocrinology, 2019 Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the effect of BMov

First Baby Born in Brazil after Simultaneous Diagnosis through Non-Invasive and Conventional PGT-A
Revista Brasileira de Ginecologia e Obstetrícia, 2022 Non-invasive preimplantation genetic testing for aneuploidies (niPGT-A) aiming to assess cell-free embryonic DNA in spent culturemedia is promising, especially because it might overcome the diminished rates of implantation caused by the inadequate ...

Prostaglandins in Swine Blastocysts [PDF]
Biology of Reproduction, 1983 The activity of phospholipase A2 (PLA2) and the content of prostaglandins (PGF and PGE-A) in swine blastocysts were determined on Days 7 through 14 of gestation by using radioenzymatic and radioimmunoassay techniques. Both PLA2 activity and PG content increased in the blastocyst with age.

Developmental Potential of Abnormally Fertilized Oocytes and the Associated Clinical Outcomes
Frontiers in Physiology, 2020 This study aims to investigate the embryo development potential of extending the culture of abnormally fertilized zygotes with no pronuclear (0PN), monopronuclear (1PN), and poor-quality day 3 embryos and to determine the associated clinical outcomes ...

Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]
, 2017 DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive
