Glutamine transport by mouse inner cell masses [PDF]

open access: yesReproduction, 1995
Abstract Mouse blastocysts take up glutamine by specific transport systems. Glutamine is an important precursor for macromolecular synthesis and a potential alternative fuel to glucose. This study compared glutamine uptake in blastocysts and isolated inner cell masses and characterized the major participating systems in the latter ...

Ploidy Testing of Blastocoel Fluid for Screening May Be Technically Challenging and More Invasive Than That of Spent Cell Culture Media

open access: yesFrontiers in Physiology, 2022
BackgroundRecent studies have demonstrated that both blastocoel fluid (BF) and spent cell culture media (SCM) have potential as materials for non-invasive or less-invasive pre-implantation genetic analysis.

A Shorter Equilibration Period Improves Post-Warming Outcomes after Vitrification and in Straw Dilution of In Vitro-Produced Bovine Embryos

open access: yesBiology, 2021
This study was designed to the optimize vitrification and in-straw warming protocol of in vitro-produced bovine embryos by comparing two different equilibration periods, short equilibrium (SE: 3 min) and long equilibrium (LE: 12 min).

Characterizing Inner Pressure and Stiffness of Trophoblast and Inner Cell Mass of Blastocysts [PDF]

open access: yesBiophysical Journal, 2018
It has long been recognized that mechanical forces underlie mammalian embryonic shape changes. Before gastrulation, the blastocyst embryo undergoes significant shape changes, namely, the blastocyst cavity emerges and expands, and the inner cell mass (ICM) forms and changes in shape.

Cell fate clusters in ICM organoids arise from cell fate heredity and division: a modelling approach

open access: yesScientific Reports, 2020
During the mammalian preimplantation phase, cells undergo two subsequent cell fate decisions. During the first decision, the trophectoderm and the inner cell mass are formed.

Replacement of inner cell mass in mouse

open access: yesChinese Science Bulletin, 2003
The intraor inter-strain reconstituted blastocysts were produced by replacing the inner cell mass of Kunming mouse blastocysts with that of Kunming or C57BL/6 mouse strain blastocysts. A total of 192 intra-strain reconstituted blastocysts were transferred into 17 pseudo-pregnant Kunming mice, and 2 reconstituted embryos were developed into term; while ...

Role of the inner cell mass in controlling implantation in the mouse [PDF]

open access: yesReproduction, 1976
Summary. Studies with mouse blastocysts and trophoblastic vesicles showed that the inner cell mass was not essential for controlling trophoblast activity during delay of implantation.

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

open access: yesFrontiers 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 ...

Generating porcine chimeras using inner cell mass cells and parthenogenetic preimplantation embryos. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: The development and validation of stem cell therapies using induced pluripotent stem (iPS) cells can be optimized through translational research using pigs as large animal models, because pigs have the closest characteristics to humans among ...

Diagnostic efficiency of blastocyst culture medium in noninvasive preimplantation genetic testing

open access: yesF&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 ...
