Human induced pluripotent stem cells were generated from a Beckwith-Wiedemann syndrome patient to investigate the relationship between abnormal imprinting gene expression and cellular phenotypes for understanding disease pathogenesis.

The paper reports the generation of a human induced pluripotent stem cell (iPSC) line from peripheral blood mononuclear cells of one affected individual from a family with clustering of Beckwith-Wiedemann syndrome (BWS), a genomic imprinting disorder caused by abnormalities in chromosome 11p15.5. Using a non-integrating reprogramming method, the authors show that the resulting iPSC line can be differentiated into multiple lineages to relate abnormal imprinting gene expression to cellular phenotypes, aiming to clarify BWS pathogenic mechanisms. A stated caveat is that the work began as a preprint and is described as not yet peer reviewed in that stage. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Beckwith-Wiedemann syndrome (BWS) is a human genomic imprinting disorder caused by an imprinting abnormality in the chromosome 11p15.5 region. It is rare and sporadic with unclear etiology and pathogenesis. We identified a family with a clustering of BWS cases. An induced pluripotent stem cell line (BWS iPSC) was generated from peripheral blood mononuclear cells (PBMCs) of one affected family member using a non-integrating reprogramming method. This cell line could be further differentiated into multiple lineages, enabling us to determine the relationship of the expression of abnormal imprinting genes in BWS to cellular phenotypes, thus elucidating the pathogenic mechanisms of BWS. In future, the multi-lineage cells can be used to test various innovative therapies, providing conceptual validation for the treatment of BWS.
