The retinal pigment epithelium (RPE) cell, located between the neural retina and choriocapillaris, is vital for retinal maintenance and photoreceptor function. Human embryonic stem cells (hESCs) provide a limitless source of RPE cells for transplantation. Using CRISPR/Cas9, we inserted a fusion of the BEST1 promoter (an RPE-specific marker) and the EGFP gene into the AAVS1 locus to track differentiation in hESC-induced RPE (hESC-iRPE). The resulting gene-edited line, WAe009-A-2 M, maintained a normal karyotype, expressed pluripotency markers, and demonstrated differentiation potential, making it invaluable for RPE development and therapeutic research.
视网膜色素上皮（RPE）细胞位于神经视网膜和脉络膜毛细血管之间，对视网膜维持和光感受器功能至关重要。人类胚胎干细胞（hESCs）为移植提供了无限的RPE细胞来源。我们使用CRISPR/Cas9将BEST1启动子（一种RPE特异性标志物）与EGFP基因的融合体插入AAVS1位点，以追踪hESC诱导的RPE（hESC-iRPE）中的分化情况。产生的基因编辑系WAe009-A-2 M保持正常核型，表达多能性标志物，并表现出分化潜能，这使其在RPE发育和治疗研究中具有极高价值。
