Pregnancy Outcomes and Postnatal Health From Transferred Mosaic Embryos Following Preimplantation Genetic Testing for Aneuploidy

open access: yesiNew Medicine, EarlyView.
This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

Position- and Hippo signaling-dependent plasticity during lineage segregation in the early mouse embryo

open access: yeseLife, 2017
The segregation of the trophectoderm (TE) from the inner cell mass (ICM) in the mouse blastocyst is determined by position-dependent Hippo signaling. However, the window of responsiveness to Hippo signaling, the exact timing of lineage commitment and the

Maternal and neonatal outcomes associated with trophectoderm biopsy

open access: yesFertility and Sterility, 2019
(Abstracted from Fertil Steril 2019;112:283–290) Despite a widespread increase in the use of preimplantation genetic testing (PGT), there remains inconclusive examination of maternal and neonatal outcomes after pregnancy achieved through in vitro fertilization (IVF) with PGT.

Predicting live birth following single euploid frozen‐embryo transfer via β‐hCG dynamics: iHOPE prognostic model with external validation

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives To determine the prognostic value of serum β‐human chorionic gonadotropin (β‐hCG) for predicting live birth following single euploid frozen‐embryo transfer (FET), and to develop and validate a prognostic model (iHOPE) for this purpose. Methods This retrospective cohort study used data from two large fertility practices.

Optimized protocol for naive human pluripotent stem cell-derived trophoblast induction

open access: yesSTAR Protocols, 2021
Summary: Human trophoblasts arise from the morula as trophectoderm, which differentiates into cytotrophoblast, syncytiotrophoblast, and extravillous trophoblast after implantation.

Distribution of endothelial cell protein C/activated protein C receptor (EPCR) during mouse embryo development. [PDF]

open access: yes, 2002
The endothelial cell protein C receptor (EPCR) augments protein C activation by the thrombomodulin.thrombin complex. Deletion of the EPCR gene in mice has been reported to lead to embryonic lethality before embryonic day 10 (E10.0). To identify potential

Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]

open access: yes, 2019
During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Sox2 Is Essential for Formation of Trophectoderm in the Preimplantation Embryo

open access: yesPLoS ONE, 2010
In preimplantation mammalian development the transcription factor Sox2 (SRY-related HMG-box gene 2) forms a complex with Oct4 and functions in maintenance of self-renewal of the pluripotent inner cell mass (ICM). Previously it was shown that Sox2-/- embryos die soon after implantation.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

open access: yesAndrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.
