Association between blastocyst morphology and outcome of single-blastocyst transfer [PDF]

Reproductive BioMedicine Online, 2013
The aim of this study was to assess the ability of three individual blastocyst morphology parameters - expansion and hatching (EH) stage, inner cell mass (ICM) grade and trophectoderm grade - to predict outcome of a cycle with single-blastocyst transfer. The study was a secondary analysis of data prospectively collected in a large multicentre trial.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Effects of Nonablative Er‐YAG Laser on Human Endometrial Stromal Cells (hESCs): A Pilot Study

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives To investigate the thermo‐chemical effects of nonablative Er:YAG laser on human endometrial stromal cells (hESCs). Materials and Methods In this laboratory based study, for the hESCs cultures, endometrial tissue biopsy samples were obtained from three fertile women in the late proliferative phase.

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

Zdravniški 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.

Effects of Heat Stress on the Developmental Competence of Bovine Cumulus-Oocyte Complex During in vitro Maturation

Journal of Animal Reproduction and Biotechnology, 2017
The elevated temperature and high humidity has been known as main reason for heat stress on animals and cause detrimental effects on productivity of organisms and physiological conditions of normal bioactivities.

Growth-factor-mediated coupling between lineage size and cell fate choice underlies robustness of mammalian development

eLife, 2020
Precise control and maintenance of population size is fundamental for organismal development and homeostasis. The three cell types of the mammalian blastocyst are generated in precise proportions over a short time, suggesting a mechanism to ensure a ...

Pregnancy and birth outcomes following fresh or vitrified embryo transfer according to blastocyst morphology and expansion stage, and culturing strategy for delayed development.

Human Reproduction, 2016
STUDY QUESTION How do live birth rates (LBRs), following fresh and vitrified/warmed embryo transfer, compare according to morphological grade, developmental stage and culturing strategy of human blastocysts in vitro? SUMMARY ANSWER Equivalent LBRs were

Signaling Centers Drive Brachyury Dynamics and Lineage Commitment in mESC Aggregates

FASEB BioAdvances, EarlyView.
We used a mouse embryonic stem cell aggregate model to compare the use of Chiron and BMP4 signaling as pulses (applied to the whole aggregate) or signaling centers (applied to part of the aggregate). BMP4 as a pulse was shown to drive neural differentiation, with Chiron inhibiting this effect.

Correlation between standard blastocyst morphology, euploidy and implantation: an observational study in two centers involving 956 screened blastocysts.

Human Reproduction, 2014
STUDY QUESTION Does conventional blastocyst morphological evaluation correlate with euploidy (as assessed by comprehensive chromosome screening (CCS) of trophectoderm (TE) biopsies) and implantation potential? SUMMARY ANSWER A moderate relation between

Histological cut of a paraffin-embedded blastocyst: Optimized protocol for murine blastocysts

MethodsX, 2020
Paraffin-embedded tissues have been used for research and therapeutic applications for decades, as they represent a valuable tool in histology and for molecular analysis, as well as being a way to preserve tissue samples for long periods at a low cost.
