Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová, Séverine Marguerite Urfer

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

Functional analysis of RIP toxins from the Drosophila endosymbiont Spiroplasma poulsonii

Bruno Lemaitre, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

BackgroundInsects frequently live in close relationship with symbiotic bacteria that carry out beneficial functions for their host, like protection against parasites and viruses. However, in some cases, the mutualistic nature of such associations is put in ...

In vitro modeling of complex microenvironmental regulation of stem cells

Yoji Tabata

Although stem cells hold tremendous potential for clinical applications, their in vitro manipulation remains very challenging. In vivo, stem cells reside in intricate 3D microenvironments, termed niche, in which many local and systemic extrinsic factors ar ...

Retinoic acid signaling organizes endodermal organ specification along the entire antero-posterior axis

Anne Grapin-Botton

BACKGROUND: Endoderm organ primordia become specified between gastrulation and gut tube folding in Amniotes. Although the requirement for RA signaling for the development of a few individual endoderm organs has been established a systematic assessment of i ...

Key events of pancreas formation are triggered in gut endoderm by ectopic expression of pancreatic regulatory genes

Anne Grapin-Botton

The mechanisms by which the epithelium of the digestive tract and its associated glands are specified are largely unknown. One clue is that several transcription factors are expressed in specific regions of the endoderm prior to and during organogenesis. P ...

Hox-4 gene expression in mouse/chicken heterospecific grafts of signalling regions to limb buds reveals similarities in patterning mechanisms

Denis Duboule

The products of Hox-4 genes appear to encode position in developing vertebrate limbs. In chick embryos, a number of different signalling regions when grafted to wing buds lead to duplicated digit patterns. We grafted tissue from the equivalent regions in m ...
