Abstract

We generated iPS cells from human dermal fibroblasts (HDFs) of Fabry disease using a Sendai virus (SeVdp) vector; this method has been established by Nakanishi et al. for pathogenic evaluation. We received SeVdp vector from Nakanishi and loaded it simultaneously with four reprogramming factors (Klf4, Oct4, Sox2, and c-Myc) to HDFs of Fabry disease; subsequently, we observed the presence of human iPS-like cells. The Sendai virus nucleocapsid protein was not detected in the fibroblasts by RT-PCR analysis. Additionally, we confirmed an undifferentiated state, alkaline phosphatase staining, and the presence of SSEA-4, TRA-1-60, and TRA-1-81. Moreover, ultrastructural features of these iPS cells included massive membranous cytoplasmic bodies typical of HDFs of Fabry disease. Thus, we successfully generated human iPS cells from HDFs of Fabry disease that retained the genetic conditions of Fabry disease; also, these abnormal iPS cells could not be easily differentiated into mature cell types such as neuronal cells, cardiomyocytes, etc. because of a massive accumulation of membranous cytoplasmic bodies in lysosomes, possibly the persistent damages of intracellular architecture.
