Single-Cell Landscape of Transcriptional Heterogeneity and Cell Fate Decisions during Mouse Early Gastrulation

Cell Reports, 2017
Summary: The mouse inner cell mass (ICM) segregates into the epiblast and primitive endoderm (PrE) lineages coincident with implantation of the embryo. The epiblast subsequently undergoes considerable expansion of cell numbers prior to gastrulation.

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

Advanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

Developmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Live imaging of whole mouse embryos during gastrulation: migration analyses of epiblast and mesodermal cells. [PDF]

PLoS ONE, 2013
During gastrulation in the mouse embryo, dynamic cell movements including epiblast invagination and mesodermal layer expansion lead to the establishment of the three-layered body plan.

Revealing cell populations catching the early stages of human embryo development in naive pluripotent stem cell cultures

Stem Cell Reports, 2023
Summary: Naive human pluripotent stem cells (hPSCs) are defined as the in vitro counterpart of the human preimplantation embryo’s epiblast and are used as a model system to study developmental processes.

Membrane lipid metabolism as a regulatory frontier in neural crest biology: Roles for sphingolipids, cholesterol, and lipid rafts

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Engineering a Computable Epiblast for in silico Modeling of Developmental Toxicity

Reproductive Toxicology, 2023
Developmental hazard evaluation is an important part of assessing chemical risks during pregnancy. Toxicological outcomes from prenatal testing in pregnant animals result from complex chemical-biological interactions, and while New Approach Methods (NAMs) based on in vitro bioactivity profiles of human cells offer promising alternatives to animal ...

Suppression of ERK signalling promotes pluripotent epiblast in the human blastocyst

Nature Communications
Studies in the mouse demonstrate the importance of fibroblast growth factor (FGF) and extra-cellular receptor tyrosine kinase (ERK) in specification of embryo-fated epiblast and yolk-sac-fated hypoblast cells from uncommitted inner cell mass (ICM) cells ...

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

Andrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to
