A Critical Examination of the Question of Personhood in Stem Cell Research [PDF]

open access: yes, 2016
Stem cell research programme has been celebrated world over as the most promising medical research in the 21st century. However, the method of stem cell research involves the use and unavoidable destruction of human embryo.

Interactome comparison of human embryonic stem cell lines with the inner cell mass and trophectoderm [PDF]

open access: yes, 2018
Networks of interacting co-regulated genes distinguish the inner cell mass (ICM) from the differentiated trophectoderm (TE) in the preimplantation blastocyst, in a species specific manner.

CRISPR Screening Reveals a Novel Role for FOXH1 in Regulating Pluripotency of Porcine Embryonic Stem Cells

open access: yesAdvanced Science, EarlyView.
This study performs dual CRISPR screens in pEPSCs. Fitness screening identifies essential genes for viability, while FACS‐based screening uncovers core pluripotency factors. It highlights FOXH1 as a key regulator that maintains the stem cell state through a dual‐action mechanism: preserving pluripotency by enhancing chromatin accessibility and ...

Blastocyst-induced changes in the bovine endometrial transcriptome.

open access: yesReproduction, 2018
The objectives of this study were (i) to determine whether blastocyst-induced responses in endometrial explants were detectable after 6- or 24-h co-culture in vitro; (ii) to test if direct contact is required between embryos and the endometrial surface ...

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Pluripotent Stem Cells as a Model for Human Embryogenesis

open access: yesCells, 2023
Pluripotent stem cells (PSCs; embryonic stem cells and induced pluripotent stem cells) can recapitulate critical aspects of the early stages of embryonic development; therefore, they became a powerful tool for the in vitro study of molecular mechanisms ...

Top quality blastocyst formation rates in relation to progesterone levels on the day of oocyte maturation in GnRH antagonist IVF/ICSI cycles

open access: yesPLoS ONE, 2017
Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a “freeze-all” strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity.

Green‐to‐red spectral labeling: A novel polysynaptic retrograde tracing strategy in the marker footprint mouse model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
To compensate for the fluorescence loss in rabies virus–derived neuronal tracing tools caused by non‐cytolytic immune clearance (NCLIC) in retrograde tracing, we developed a novel green‐to‐red spectral labeling (GTR) strategy based on the NCLIC phenomenon and developed a novel marker footprints mouse to support the strategy.

Mitochondrial reactive oxygen species regulate mitochondrial biogenesis in porcine embryos

open access: yesThe Journal of Reproduction and Development, 2021
The number of mitochondria in blastocysts is a potential marker of embryo quality. However, the molecular mechanisms governing the mitochondrial number in embryos are unclear.
