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

open access: yesRevista 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

open access: yesStem 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

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 ...

Cell arrest and cell death in mammalian preimplantation development [PDF]

open access: yes, 2011
The causes, modes, biological role and prospective significance of cell death in preimplantation development in humans and other mammals are still poorly understood.

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

open access: yesiScience, 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 ...

A simple matter of life and death : the trials of postnatal beta-cell mass regulation [PDF]

open access: yes, 2012
Pancreatic beta-cells, which secrete the hormone insulin, are the key arbiters of glucose homeostasis. Defective beta-cell numbers and/or function underlie essentially all major forms of diabetes and must be restored if diabetes is to be cured. Thus, the

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

open access: yesFrontiers 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

open access: yesArquivo 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]

open access: yes, 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.

Energy- and temperature-dependent transport of integral proteins to the inner nuclear membrane via the nuclear pore [PDF]

open access: yes, 2004
Resident integral proteins of the inner nuclear membrane (INM) are synthesized as membrane-integrated proteins on the peripheral endoplasmic reticulum (ER) and are transported to the INM throughout interphase using an unknown trafficking mechanism.
