Generation and characterization of two human induced pluripotent stem cell lines from myotonic dystrophy type 1 patients

Summary

The neuromuscular disorder myotonic dystrophy Type 1 (DM1) is brought on by CTG trinucleotide repeat expansions in the dystrophia myotonica-protein kinase (DMPK) gene, which leads to progressive myotonia and muscle weakness. We used Sendai virus reprogramming to generate two induced pluripotent stem cell (iPSC) lines (SCVIi134-A and SCVIi137-A) from peripheral blood mononuclear cells (PBMCs) of female DM1 patients carrying CTG repeat expansion. Both lines have normal karyotypes, show expression of undifferentiated human iPSC state markers, and differentiate into all three germ layers. These iPSC lines provide a platform for studying RNA toxicity at the molecular level and for drug development. Copyright © 2026. Published by Elsevier B.V.
