Substrate stiffness affects early differentiation events in embryonic stem cells [PDF]

open access: yesEuropean Cells & Materials, 2009
Embryonic stem cells (ESC) are both a potential source of cells for tissue replacement therapies and an accessible tool to model early embryonic development.

Alternative splicing dynamics during gastrulation in mouse embryo

open access: yesScientific Reports
Alternative splicing (AS) plays an essential role in development, differentiation and carcinogenesis. However, the mechanisms underlying splicing regulation during mouse embryo gastrulation remain unclear.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Gastrulation in the sea urchin

open access: yes, 2020
Gastrulation is arguably the most important evolutionary innovation in the animal kingdom. This process provides the basic embryonic architecture, an inner layer separated from an outer layer, from which all animal forms arise. An extraordinarily simple and elegant process of gastrulation is observed in the sea urchin embryo. The cells participating in

Comparative Expression of Zebrafish Lats1 and Lats2 and Their Implication in Gastrulation Movements

open access: yes, 2009
Large tumor suppressor (Lats) is a Ser/Thr kinase, and it presents an important function in tumor suppression. lats was originally identified in Drosophila and recently in mammals. In mammals, it contains two homologues, lats1 and lats2.

A mechanochemical model recapitulates distinct vertebrate gastrulation modes [PDF]

open access: yes, 2023
During vertebrate gastrulation, an embryo transforms from a layer of epithelial cells into a multilayered gastrula. This process requires the coordinated movements of hundreds to tens of thousands of cells, depending on the organism. In the chick embryo,

Micropattern differentiation of mouse pluripotent stem cells recapitulates embryo regionalized cell fate patterning

open access: yeseLife, 2018
During gastrulation epiblast cells exit pluripotency as they specify and spatially arrange the three germ layers of the embryo. Similarly, human pluripotent stem cells (PSCs) undergo spatially organized fate specification on micropatterned surfaces ...

Time space and single-cell resolved tissue lineage trajectories and laterality of body plan at gastrulation

open access: yesNature Communications, 2023
Understanding of the molecular drivers of lineage diversification and tissue patterning during primary germ layer development requires in-depth knowledge of the dynamic molecular trajectories of cell lineages across a series of developmental stages of ...

Morphological changes and two Nodal paralogs drive left-right asymmetry in the squamate veiled chameleon (C. calyptratus)

open access: yesFrontiers in Cell and Developmental Biology, 2023
The ancestral mode of left-right (L-R) patterning involves cilia in the L-R organizer. However, the mechanisms regulating L-R patterning in non-avian reptiles remains an enigma, since most squamate embryos are undergoing organogenesis at oviposition.

Niche‐Mediated Neural Priming Enables Robust and Scalable Generation of Human Choroid Plexus Organoids

open access: yesAdvanced Science, EarlyView.
Compared to E8, mTeSR1 culture downregulated WNT and TGF‑β signaling, and upregulated neural differentiation pathways, enhancing neural priming. Under skin organoid induction conditions, mTeSR1‑cultured hESCs generated organoids with significantly higher neuroepithelial differentiation.
