NSUN2‐Mediated m5C Modification of TGFB1 in Trophoblasts Remodels Macrophage Function to Prevent URSA

open access: yesAdvanced Science, EarlyView.
NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...

Trophectoderm Biopsy: Present State of the Art

open access: yesGenes
Trophectoderm (TE) biopsy is at present the most widely used procedure for preimplantation genetic testing (PGT). At the blastocyst stage, more TE cells (five to seven) can be obtained for genetic analysis. While removing TE cells and not touching the inner cell mass (ICM), the procedure is less invasive.

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

Implementation of Noninvasive Preimplantation Genetic Testing for Aneuploidy with Spent Blastocyst Medium into Clinical and Laboratory Practice: The First Successful Experience in Taiwan

open access: yesFertility & Reproduction, 2023
Noninvasive preimplantation genetic testing for aneuploidy (niPGT-A) using cell-free DNA (cfDNA) present in the spent blastocyst medium (SBM) of human blastocysts has emerged as an alternative for classical preimplantation genetic testing for aneuploidy (

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

open access: yesAdvanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Perceptions of trophectoderm as a sentinel for embryo selection [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2014
The archives of mammalian embryology are punctuated by landmark studies covering a rich tradition of technological bravado that spans 75 years. The most primordial perceptions of preimplantation embryo morphology were recorded at the Carnegie Institute for Embryology in Baltimore by the likes of Corner, Streeter, Hauser, Hartmann and others in the ...

The nuclear lamina couples mechanical forces to cell fate in the preimplantation embryo via actin organization

open access: yesNature Communications, 2023
During preimplantation development, contractile forces generated at the apical cortex segregate cells into inner and outer positions of the embryo, establishing the inner cell mass (ICM) and trophectoderm.

ViTAMIn‐O: Democratizing Computer Vision‐Based Machine Learning for Stem Cell Research

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a fully open generalist computer vision model for predicting the differentiation outcomes of stem cell‐based model systems, together with its code‐free deployment platform, ColabViTAMIn‐O. It is benchmarked against various architectures, datasets, and training protocols.

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.

C/EBPα instructs trophectoderm and pluripotency through the II6 pathway

open access: yes, 2021
Continuous C/EBPa expression converts B cells into macrophages while its transient upregulation before the Yamanaka factors yields highly efficient iPSC reprogramming. C/EBP members regulate Il6 pathway genes and IL-6 signaling participates in macrophage
