Generation of induced pluripotent stem line (MIPTi001-A) derived from patient with X-linked adrenoleukodystrophy (X-ALD)

Abstract

X-linked adrenoleukodystrophy is a metabolic disease associated with mutations in the ABCD1 gene (ATP-binding cassette subfamily D). Numerous pathogenic variants in this gene lead to a wide spectrum of symptoms, including adrenal insufficiency, slowly progressive dying-back axonopathy and demyelination of the central nervous system in specific phenotypes.The induced pluripotent stem cell line was derived from a patient diagnosed with x-ALD. Due to the complexity of developing working therapy based on animal models, it’s crucial to obtain the cell model directly from patients. Peripheral blood mononuclear cells (PBMCs) isolated from the donor’s whole blood were reprogrammed into induced pluripotent stem cells and then characterized. Expression of pluripotency markers SSEA4, TRA-1-60, SOX2, OCT4 is proven quantitatively and qualitatively, iPSCs demonstrate the ability to differentiate into three germ layers and the absence of Sendai virus expression factors.
