Génération de sept lignées iPSC à partir de cellules mononucléées du sang périphérique pouvant être utilisées pour étudier les "troubles du spectre de l'autisme"

Aperçu: G.M.
Nous avons généré et caractérisé sept lignées de cellules souches pluripotentes induites par l'homme (iPSC) dérivées de cellules mononucléées du sang périphérique (PBMC) appartenant à une seule famille, y compris des personnes non atteintes et affectées cliniquement diagnostiquées avec un "trouble du spectre de l'autisme" (dTSA). La reprogrammation des PBMC a été réalisée à l'aide du virus Sendai non intégratif contenant les facteurs de reprogrammation POU5F1 (OCT4), SOX2, KLF4 et MYC. 
Toutes les lignées iPSC présentaient un caryotype normal et la pluripotence était validée par immunofluorescence, cytométrie en flux et leur capacité à se différencier dans les trois couches germinales embryonnaires. 
Ces lignées iPSC constituent une ressource précieuse pour l’étude des mécanismes moléculaires sous-jacents des TSA.

Abstract

We have generated and characterized seven human induced pluripotent stem cell (iPSC) lines derived from peripheral blood mononuclear cells (PBMCs) from a single family, including unaffected and affected individuals clinically diagnosed with Autism Spectrum Disorder (ASD). The reprogramming of the PBMCs was performed using non-integrative Sendai virus containing the reprogramming factors POU5F1 (OCT4), SOX2, KLF4 and MYC. All iPSC lines exhibited a normal karyotype and pluripotency was validated by immunofluorescence, flow cytometry and their ability to differentiate into the three embryonic germ layers. These iPSC lines are a valuable resource to study the molecular mechanisms underlying ASD.
