Effect of equilibration time on clinical and neonatal outcomes in human blastocysts vitrification

open access: yesReproductive Medicine and Biology, 2020
Purpose Prolonged exposure to equilibration solutions may be detrimental to an embryo's developmental potential, whereas a shorter exposure may affect the penetration of cryoprotectants into blastomeres.

The effect of leukaemia inhibitory factor (LIF) on bovine embryo development in vitro : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

open access: yes, 1995
The aim of the study was to investigate the effect of Leukaemia Inhibitory Factor (LIF) either during in vitro maturation (IVM) or in vitro culture (IVC) on bovine embryo development. Three main experiments were conducted using oocytes aspirated from 2-8

The Transcription Factor OVOL2 Represses ID2 and Drives Differentiation of Trophoblast Stem Cells and Placental Development in Mice

open access: yesCells, 2020
Trophoblasts are the first cell type to be specified during embryogenesis, and they are essential for placental morphogenesis and function. Trophoblast stem (TS) cells are the progenitor cells for all trophoblast lineages; control of TS cell ...

POSSIBLILTIES FOR A SINGLE EMBRYO TRANSFER IN AN IN VITRO FERTILIZATION PROGRAMME

open access: yesZdravniški Vestnik, 2003
Background. Since in in vitro fertilization two embryos – blastocysts are routinely transferred, the twin pregnancy rates are higher than in the general population.
