Human fibroblast cells collected from a 3-year old, female Rett Syndrome patient with a 32 bp deletion in the X-linked MECP2 gene were obtained from the Coriell Institute. Fibroblasts were reprogrammed to iPSC cells using a Sendai-virus delivery system expressing human KOSM transcription factors. Cell-line pluripotency was demonstrated by gene expression, immunocytochemistry, in-vitro differentiation trilineage capacity and was of normal karyotype. Interestingly, subsequent clones retained the epigenetic memory of the parent fibroblasts allowing for the segregation of wild-type and mutant expressing clones. This MECP2 mutant expressing clone may serve as a model for investigating MECP2 reactivation in Rett's Syndrome.
