Day-3-embryo fragmentation is associated with singleton birth weight following fresh single blastocyst transfer: A retrospective study

Frontiers in Endocrinology, 2022
BackgroundPrevious studies have arguably associated poor embryo morphology with low birth weight in singletons following single embryo transfer. However, the association between birth weight and specific morphological features in the cleavage stage ...

Effect of follicular fluid supplementation during in vitro maturation on total cell number in bovine blastocysts produced in vitro

Revista Brasileira de Zootecnia, 2014
This study evaluated the influence of follicular fluid (FF) added to the maturation medium on the quality of bovine embryos produced in vitro. In the first experiment, oocytes were matured in media containing five different FF concentrations with ...

Transcriptomic profiling of porcine pluripotency identifies species-specific reprogramming requirements for culturing iPSCs

Stem Cell Research, 2019
Porcine embryonic and induced pluripotent stem cells (ESCs; iPSCs) have proven difficult to derive and maintain in vitro. This may be due to inappropriate culturing conditions and incomplete activation of proper pluripotency networks.

Diagnostic efficiency of blastocyst culture medium in noninvasive preimplantation genetic testing

F&S Reports, 2021
Objective: To evaluate the diagnostic efficiency of spent blastocyst culture medium (BCM) in noninvasive preimplantation genetic testing (niPGT) by comparing the karyotype concordance with corresponding inner cell mass (ICM) among initial trophectoderm ...

The salt-and-pepper pattern in mouse blastocysts is compatible with signaling beyond the nearest neighbors

iScience, 2023
Summary: Embryos develop in a concerted sequence of spatiotemporal arrangements of cells. In the preimplantation mouse embryo, the distribution of the cells in the inner cell mass evolves from a salt-and-pepper pattern to spatial segregation of two ...

Leukemia Inhibitory Factor Stimulates Primitive Endoderm Expansion in the Bovine Inner Cell Mass

Frontiers in Animal Science, 2021
Previous work determined that bovine interleukin-6 (IL6) increases inner cell mass (ICM), primitive endoderm (PE), and total cell number in in vitro produced (IVP) bovine blastocysts.

Bovine conceptus of Bos indicus produced by somatic cell nuclear transfer and parthenogenesis present morphological variations since the blastocyst stage

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2015
In cattle, embryo development is characterized by the appearance of two distinct cell layers, the trophectoderm and the inner cell mass. The latter will undergo differentiation to form the embryonic disc consisting of the epiblast and hypoblast.

Cell Lineage Allocation Within the Inner Cell Mass of the Mouse Blastocyst [PDF]

, 2012
At the time of implantation, the early mouse embryo consists of three distinct cell lineages: the epiblast (EPI), primitive endoderm (PrE), and trophectoderm (TE). Here we will focus on the EPI and PrE cell lineages, which arise within the inner cell mass (ICM) of the blastocyst.

Trophectoderm, Inner Cell Mass, and Expansion Status for Live Birth Prediction After Frozen Blastocyst Transfer: The Winner Is Trophectoderm

Life
Despite advancements in technologies such as time-lapse microscopy and artificial intelligence, the gold standard for embryo selection still relies on standard morphological assessment. Several studies have investigated the correlation between blastocyst

The location of "8"-shaped hatching influences inner cell mass formation in mouse blastocysts. [PDF]

PLoS ONE, 2017
The hatching of a blastocyst where the blastocyst portions on the inside and the outside of the zona pellucida feature a figure-of-eight shape is termed "8"-shaped hatching; this type of hatching has been reported to affect the proper presentation of the
