Abstract Gaucher Disease (GD) type 3 is a neurological form of a multisystemic autosomal recessive disorder belonging to the group of lysosomal storage diseases. Mutations in glucocerebrosidase 1 (GBA1) commonly lead to abnormal protein and GD, heterozygosity is a genetic risk factor for Parkinson's disease. This work describes the use of a non-integrative approach using Sendai Virus delivery to establish iPSCs from fibroblasts from a GD type 3 patient. Differentiation of induced Pluripotent Ste...

Mutations and inadequate methylation profiles of CITED2 are associated with human congenital heart disease (CHD). In mouse, Cited2 is necessary for embryogenesis, particularly for heart development, and its depletion in embryonic stem cells (ESC) impairs cardiac differentiation. We have now determined that Cited2 depletion in ESC affects the expression of transcription factors and cardiopoietic genes involved in early mesoderm and cardiac specification. Interestingly, the supplementation of the ...

The CITED family of transcriptional modulators plays multiple roles in the development of vertebrates. These proteins are characterized by the conservation of a carboxy-terminal domain which defines this family and has a high affinity for the transcriptional co-activators CBP/p300. In humans, mutations in some CITED genes or deregulation of their expression are associated with developmental anomalies. In particular, CITED2 dysfunction has been associated with congenital heart disease. Although m...

Transcriptomic data have become a fundamental resource for stem cell (SC) biologists as well as for a wider research audience studying SC-related processes such as aging, embryonic development and prevalent diseases including cancer, diabetes and neurodegenerative diseases. Access and analysis of the growing amount of freely available transcriptomics datasets for SCs, however, are not trivial tasks. Here, we present StemMapper, a manually curated gene expression database and comprehensive resour...

Abstract Cited2 plays crucial roles in mouse embryonic stem cells self-renewal, the initiation of the somatic reprogramming process into induced pluripotent stem cells (iPSC) and the suppression of cell senescence. Here, we investigated the potential of CITED2 expression in combination with the Oct4, Sox2, Klf4 and c-Myc factors for reprogramming of primary mouse embryonic fibroblasts (MEF) at passage 2 and 4. The ectopic CITED2 expression in primary MEF prior to the onset of the reprogramming p...

Abstract Neurogenic niches constitute a powerful endogenous source of new neurons that can be used for brain repair strategies. Neuronal differentiation of these cells can be regulated by molecules such as retinoic acid (RA) or by mild levels of reactive oxygen species (ROS) that are also known to upregulate RA receptor alpha (RARα) levels. Data showed that neural stem cells from the subventricular zone (SVZ) exposed to blue light (405 nm laser) transiently induced NADPH oxidase-dependent ROS, r...

Conducting polymer electrodes based on poly (3, 4 ethylenedioxythiophene):polystyrene sulfonate were used to record electrophysiological signals from autonomous cardiac contractile cells present in embryoid bodies. Signal detection was carried out by measuring the displacement current across the polymer/electrolyte double-layer capacitance, and compared with voltage detection. While for relatively low capacitance electrodes, the voltage amplification provides higher signal quality, and for high ...
