Project description:To investigate and compare the gene expression profile of sympathetic neurons differentiated from healthy hESCs and iPSCs from patient with Familial dysautonomia
Project description:Investigate IKAP importance in the development of neuronal cells, in order to understand Familial dysautonomia phenotype. Stable SHSY5Y cell lines, and control cells, in differentiated and un-differentiated conditions.
Project description:Exploration of transcriptome expression in 5 control and 4 familial dysautonomia (FD) human olfactory ecto-mesenchymal stem cells (hOE-MSCs) at very early (P1 and P2) and later (P5 and P9) cell passages.
Project description:Human olfactory ecto-mesenchymal stem cells (hOE-MSCs) from controls and familial dysautonomia (FD) patients were cultured in either sphere-forming conditions (ITS + EGF + bFGF) or in the presence of retinoic acid, forskolin and Sonic Hedgehog (rafnshh) for 7 days to induce neuroglial differentiation and were also treated or not with kinetin (100 mM for 48h) which corrects the aberrant splicing of IKBKAP mRNA. We used the recently described model of human olfactory ecto-mesenchymal stem cells to identify genes differentially expressed between controls and familial dysautonomia patients, and also the genes sensitive to kinetin which corrects aberrant splicing of IKBKAP mRNA

We used the recently described model of human olfactory ecto-mesenchymal stem cells to identify genes differentially expressed between controls and familial dysautonomia patients, and also the genes sensitive to kinetin which corrects aberrant splicing of IKBKAP mRNA Total RNAs were extracted from 20 samples including: 4 control and 4 FD hOE-MSCs-derived sphere cultures, 4 control and 4 FD rafnshh-treated hOE-MSCs, 4 FD rafnshh-treated hOE-MSCs in the presence of kinetin
Project description:We have generated expression profiles of induced pluripotent stem cells (iPSCs) and iPSC-derived neural crest populations from Familial Dysautonomia patients. These profiles were compared to a normal iPSC line that does not harbor the IKBKAP mutation.
Project description:Global gene expression analysis of FD-iPSC and deribved neural crest cells Here we report the derivation of patient specific Familial Dysautonomia-iPSCs and their directed differentiation into multiple cell types capable of modeling the tissue specific splicing defect in vitro.
Project description:Transcriptome analysis of the effect of RECTAS on fibroblast cells derived from a familial dysautonomia patient. We analyzed fibroblast derived from FD patient (3 control (treated with 0.1% DMSO) and 3 treated (treated with 2 M-BM-5M RECTAS)) using the Affymetrix Human Exon 1.0 ST platform. Array data was processed by Affymetrix Exon Array Computational Tool. No techinical replicates were performed.
