The development of cellular models for familial hypercholesterolemia (FH) is an important direction for creating new approaches to atherosclerosis treatment. Pathogenic mutations in the LDLR gene are the main FH source. We generated an iPSC line from peripheral blood mononuclear cells of the patient with compound heterozygous c.1246C > T/c.940 + 3_940 + 6del LDLR mutation. The resulting iPSC line with confirmed patient-specific mutations maintains a normal karyotype and a typical undifferentiated state, including morphology, pluripotent gene expression, and in vitro differentiation potential. This iPSC line can be further differentiated toward relevant cells to better understand FH pathogenesis.
构建家族性高胆固醇血症(FH)细胞模型是开创动脉粥样硬化治疗新方法的一个重要方向。低密度脂蛋白受体(LDLR)基因的致病性突变是FH的主要来源。我们从一名患有复合杂合子c.1246C>T/c.940+3_940+6del LDLR突变的患者外周血单个核细胞中生成了一条诱导多能干细胞(iPSC)系。所得具有已确认的患者特异性突变的iPSC系保持正常核型和典型的未分化状态,包括形态、多能基因表达及体外分化潜能。该iPSC系可进一步分化为相关细胞,以更好地理解FH发病机制。
