The Origin of Endoderm: Transmission Electron Microscopic Point of View

open access: yesSiriraj Medical Journal, 2020
Objective: To show the transmission electron microscopic (TEM) evidence to confirm that the endoderm originates from the epiblast of the primitive streak or from other sources.

Src-Yap1 signaling axis controls the trophectoderm and epiblast lineage differentiation in mouse embryonic stem cells

open access: yesStem Cell Research, 2021
The tyrosine kinase Src is highly expressed in embryonic stem cells (ESCs) and ESC-differentiated cells, however, its functional role remains obscured. Here, we constitutively expressed Src in mouse ESCs and found these cells retained comparable levels ...

Distribution of tissue progenitors within the shield region of the zebrafish gastrula [PDF]

open access: yes, 1995
The zebrafish has emerged as an important model system for the experimental analysis of vertebrate development because it is amenable to genetic analysis and because its optical clarity allows the movements and the differentiation of individual cells to ...

Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]

open access: yes, 2019
During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Signaling Centers Drive Brachyury Dynamics and Lineage Commitment in mESC Aggregates

open access: yesFASEB BioAdvances, Volume 7, Issue 6, June 2025.
We used a mouse embryonic stem cell aggregate model to compare the use of Chiron and BMP4 signaling as pulses (applied to the whole aggregate) or signaling centers (applied to part of the aggregate). BMP4 as a pulse was shown to drive neural differentiation, with Chiron inhibiting this effect.

Dynamics of Wnt activity on the acquisition of ectoderm potency in epiblast stem cells

open access: yesDevelopment, 2019
During embryogenesis, the stringent regulation of Wnt activity is crucial for the morphogenesis of the head and brain. The loss of function of the Wnt inhibitor Dkk1 results in elevated Wnt activity, loss of ectoderm lineage attributes from the anterior ...

Dynamics of Cell Fate Decisions during Chemically Induced Multi‐Lineage Trans‐Differentiation at Single‐Cell Level

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
A critical aspect of chromosomal remodeling in small molecule‐induced multilineage trans‐differentiation(iMT) is elucidated. A dynamic atlas spanning over 35 days profiles terminal trans‐differentiated cells, which reverted to a more youthful state. This study reveals parallels between iMT and other cell fate determination processes, emphasizing an ...

In Vivo Differentiation Potential of Epiblast Stem Cells Revealed by Chimeric Embryo Formation

open access: yesCell Reports, 2012
Chimera formation after blastocyst injection or morula aggregation is the principal functional assay of the developmental potential of mouse embryonic stem cells (ESCs).

Cell lineage specific distribution of H3K27 trimethylation accumulation in an in vitro model for human implantation. [PDF]

open access: yesPLoS ONE, 2012
Female mammals inactivate one of their two X-chromosomes to compensate for the difference in gene-dosage with males that have just one X-chromosome. X-chromosome inactivation is initiated by the expression of the non-coding RNA Xist, which coats the X ...
