Generation of two induced pluripotent stem cell lines from two sporadic amyotrophic lateral sclerosis patients

Abstract

Peripheral blood mononuclear cells were obtained from two patients diagnosed with amyotrophic lateral sclerosis (ALS), a 47-year-old female and a 45-year-old male. Induced pluripotent stem cells (iPSCs) were generated using a non-integrating SeV-based method, delivering the transcription factors OCT4, SOX2, c-MYC, and KLF4. These transgene-free iPSC lines exhibited typical pluripotent cell morphology, expressed pluripotency-associated markers, and had tri-lineage differentiation potential. Both iPSC lines were free of mycoplasma contamination and displayed normal karyotypes. The availability of these two cell lines provides a promising opportunity to use sporadic ALS models for investigating the intricate pathological mechanisms of ALS.
