Three‐dimensional microscopy and image fusion reconstruction analysis of the thyroid gland during morphogenesis

FEBS Open Bio, 2021
Thyroid dysgenesis (TD) is a major cause of primary congenital hypothyroidism; however, the molecular mechanism underlying this process is unclear.

Effect of antibiotics against Mycoplasma sp. on human embryonic stem cells undifferentiated status, pluripotency, cell viability and growth [PDF]

, 2013
Human embryonic stem cells (hESCs) are self-renewing pluripotent cells that can differentiate into specialized cells and hold great promise as models for human development and disease studies, cell-replacement therapies, drug discovery and in vitro ...

Aptly Named Visceral Endoderm [PDF]

Developmental Cell, 2008
The very early mouse embryo is initially covered by a layer of cells called visceral endoderm that despite its name (visceral means associated with internal organs) was only thought to give rise to extraembryonic structures. Now, in this issue of Developmental Cell, Kwon et al. (2008) show unexpectedly that a significant population of visceral endoderm

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

Advanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Oral and Palatal Dentition of Axolotl Arises From a Common Tooth-Competent Zone Along the Ecto-Endodermal Boundary

Frontiers in Cell and Developmental Biology, 2021
Vertebrate dentitions arise at various places within the oropharyngeal cavity including the jaws, the palate, or the pharynx. These dentitions develop in a highly organized way, where new tooth germs are progressively added adjacent to the initiator ...

Metabolic Imbalance Triggers Adaptive Remodeling to Accelerate Diploidization in Murine Haploid Embryonic Stem Cells

Advanced Science, EarlyView.
In this article, Shuai and colleagues demonstrate that metabolic remodeling drives self‐diploidization in murine haploid ESCs (haESCs). Mitochondrial dysfunction and imbalanced pyruvate metabolism underlie this process. Genome‐wide screening using haESCs identifies key mitochondrial quality‐control related genes, enabling a metabolism‐based medium that

Direct comparison of distinct naive pluripotent states in human embryonic stem cells [PDF]

, 2017
Until recently, human embryonic stem cells (hESCs) were shown to exist in a state of primed pluripotency, while mouse embryonic stem cells (mESCs) display a naive or primed pluripotent state.

Highly Biomimetic Ectodermal Epithelial Organoids for Epithelial Barrier Stimulation Assays

Advanced Science, EarlyView.
ABSTRACT Evaluating the potential toxicity of pharmaceuticals and biomaterials to ectodermal epithelia, such as the oral mucosa and skin, is indispensable in pre‐clinical assessments. However, this remains a challenge primarily owing to the lack of physiologically relevant and accurate screening models.

Development of Functional Thyroid C Cell-like Cells from Human Pluripotent Cells in 2D and in 3D Scaffolds

Cells, 2021
Medullary thyroid carcinoma contributes to about 3–4% of thyroid cancers and affects C cells rather than follicular cells. Thyroid C cell differentiation from human pluripotent stem cells has not been reported.

From Multiple Congenital Anomalies to Pituitary Gland Malformation: Wide Spectrum of Clinical Features in a Family With FOXA2 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT FOXA2 (hepatocyte nuclear factor‐3β, HNF‐3β) encodes a transcriptional activator involved in early embryogenesis, particularly in the patterning and differentiation of midline structures such as the neural tube, foregut, and pituitary gland. Its role in human pathogenesis was first suspected when patients with deletion of chromosome 20p11.2 ...
