先天性小耳畸形是中耳和外耳的畸形。涉及ECR(HMX 1的耳特异性远程增强子)的重复导致不同物种的耳畸形。使用将编码OCT 4、SOX 2、NANOG、LIN 28、KLF 4和LMYC的附加型质粒电穿孔到外周血单核细胞(PBMC)中,我们产生了携带涉及ECR的复制的小耳畸形患者的诱导多能干细胞(iPSC)系。iPSC表达多能性标记,具有分化成三个胚层的潜力,并显示正常的核型。该患者特异性iPSC将用于对耳畸形的病理生理学进行建模。
Congenital microtia is a malformation of the middle and external ear. Duplications involving the ECR, an ear-specific long-range enhancer of HMX1, lead to ear malformation in different species. Use of electroporation of episomal plasmids encodes OCT4, SOX2, NANOG, LIN28, KLF4, and LMYC into peripheral blood mononuclear cells (PBMCs), we generated an induced pluripotent stem cell (iPSCs) line of a microtia patient carrying the duplication involving ECR. The iPSCs express pluripotency markers, have the potential to differentiate into three germ layers, and show the normal karyotype. This patient-specific iPSC will be used for modeling the pathophysiology of ear malformation.
