ABSTRACT
We employed a Sendai virus-based reprogramming method to transform human lymphoblastoid cell lines (LCL) derived from two individuals diagnosed with phenylketonuria (PKU) into induced pluripotent stem cells (iPSC). This reprogramming process involved the expression of the four Yamanaka factors: KLF4, OCT4, SOX2, and C-MYC. The resulting patient-specific iPSCs exhibited a normal karyotype and expressed endogenous pluripotent markers NANOG and OCT-4. Notably, these iPSCs demonstrated strong differentiation capabilities, giving rise to cell populations representing the ectoderm, endoderm, and mesoderm germ layers.

Phenylketonuria is a rare autosomal recessive metabolic disorder mainly due to a significant reduction in the enzyme phenylalanine hydroxylase, resulting in elevation of phenylalanine in the blood. Here, we have established two fibroblast-derived induced pluripotent stem cell lines using Sendai virus-based reprogramming. The established induced pluripotent stem cell lines exhibited a normal karyotype and expressed markers of pluripotency assessed through quantitative PCR, flow cytometry and immunocytochemistry. These cell lines also demonstrated the ability to differentiate into the three primary germ layers of the human body, including ectoderm, endoderm, and mesoderm.
