Soluble CD146, an innovative and non-invasive biomarker of embryo selection for in vitro fertilization. [PDF]

PLoS ONE, 2017
Although progress was made in in vitro fertilization (IVF) techniques, the majority of embryos transferred fail to implant. Morphology embryo scoring is the standard procedure for most of IVF centres for choosing the best embryo, but remains limited ...

Character of cell-free genomic DNA in embryo culture medium and the prospect of its clinical application in preimplantation genetic testing

Reproductive and Developmental Medicine, 2022
. There is increasing evidence that cell-free DNA (cfDNA) in spent culture media (SCM) can be amplified for genetic testing. Therefore, this paper reviews the characteristics of cfDNA, including its fragment size, amount, origin, as well as some factors ...

Non-inferiority of cleavage-stage versus blastocyst-stage embryo transfer in poor prognosis IVF patients (PRECiSE trial): study protocol for a randomized controlled trial

Reproductive Health, 2020
Background With improvements in in vitro culture techniques there has been a steady shift in practice to transfer embryos at the blastocyst stage (post fertilization day (p.f.d.) 5–7), when embryos reach the endometrial cavity during natural conception ...

Automated microinjection of recombinant BCL-X into mouse zygotes enhances embryo development. [PDF]

PLoS ONE, 2011
Progression of fertilized mammalian oocytes through cleavage, blastocyst formation and implantation depends on successful implementation of the developmental program, which becomes established during oogenesis.

A Nonsurgical Embryo Transfer Technique for Fresh and Cultured Blastocysts in Rats

Journal of the American Association for Laboratory Animal Science, 2020
The use of a nonsurgical embryo transfer technique in rodents eliminates the potential pain, distress, and health complications that may result from a surgical procedure and as such, represents a refinement in rodent assisted reproductive techniques. A nonsurgical technique has not been previously developed for use with rat embryos.
