How are cells instructed to form somite boundaries by the zebrafish segmentation clock?

In vertebrate embryos, the elongating body axis is patterned via the sequential and rhyth-mic production of segments from a posterior unsegmented tissue called the presomitic mesoderm (PSM). This process is controlled by a population of cellular oscillator ...

Caspase-9-mediated cleavage of vimentin attenuates the aggressiveness of leukemic NB4 cells

Cyrus Kazemiraad, Saeed Mohammadi

Vimentin is a main type 3 intermediate filament protein. It seems that abnormal expression of vimentin is contributed to the appearance of the aggressive feature of cancer cells. So that it has been reported that malignancy and epithelial-mesenchymal trans ...

Mammalian adipogenesis regulator (Areg) cells use retinoic acid signalling to be non- and anti-adipogenic in age-dependent manner

Bart Deplancke, Julie Marie Russeil, Horia Hashimi, Daniel Alpern, Maria Litovchenko, Magda Zachara, Pernille Yde Rainer, Radiana Ferrero

Adipose stem and precursor cells (ASPCs) give rise to adipocytes and determine the composition and plasticity of adipose tissue. Recently, several studies have demonstrated that ASPCs partition into at least three distinct cell subpopulations, including th ...

HOX13-dependent chromatin accessibility underlies the transition towards the digit development program

Alexandre Gauthier Aurèle Mayran

Hox genes encode transcription factors (TFs) that establish morphological diversity in the developing embryo. The similar DNA-binding motifs of the various HOX TFs contrast with the wide-range of HOX-dependent genetic programs. The influence of the chromat ...

Integration of Shh and Fgf signaling in controlling Hox gene expression in cultured limb cells

Denis Duboule, Guillaume Andrey, Patrick Schorderet, Nayuta Yakushiji

During embryonic development, fields of progenitor cells form complex structures through dynamic interactions with external signaling molecules. How complex signaling inputs are integrated to yield appropriate gene expression responses is poorly understood ...

RING1 proteins contribute to early proximal-distal specification of the forelimb bud by restricting Meis2 expression

Nayuta Yakushiji

Polycomb group (PcG) proteins play a pivotal role in silencing developmental genes and help to maintain various stem and precursor cells and regulate their differentiation. PcG factors also regulate dynamic and complex regional specification, particularly ...

Mutations in ALDH1A3 Represent a Frequent Cause of Microphthalmia/Anophthalmia in Consanguineous Families

Tatiana Favez

Anophthalmia or microphthalmia (A/M), characterized by absent or small eye, can be unilateral or bilateral and represent developmental anomalies due to the mutations in several genes. Recently, mutations in aldehyde dehydrogenase family 1, member A3 (ALDH1 ...

3D Reconstitution of the Patterned Neural Tube from Embryonic Stem Cells

Matthias Lütolf, Adrian Ranga

Inducing organogenesis in 3D culture is an important aspect of stem cell research. Anterior neural structures have been produced from large embryonic stem cell (ESC) aggregates, but the steps involved in patterning such complex structures have been ill def ...

ALDH1A3 loss of function causes bilateral anophthalmia/microphthalmia and hypoplasia of the optic nerve and optic chiasm

The major active retinoid, all-trans retinoic acid, has long been recognized as critical for the development of several organs, including the eye. Mutations in STRA6, the gene encoding the cellular receptor for vitamin A, in patients with MatthewWood syndr ...

Bigh3 Is Upregulated in Regenerating Zebrafish Fin

Zebrafish is a good model for studying regeneration because of the rapidity with which it occurs. Better understanding of this process may lead in the future to improvement of the regenerating capacity of humans. Signaling factors are the second largest ca ...
