The ISL LIM homeobox 1 (ISL1) gene belongs to the LIM/homeodomain transcription factor family and plays a pivotal role in conveying multipotent and proliferative properties of cardiac precursor cells. Mutations in ISL1 are linked to congenital heart disease. To further explore ISL1′s role in the human heart, we have created a homozygous ISL1 knockout (ISL1-KO) human embryonic stem cell line using the CRISPR/Cas9 system. Notably, this ISL1-KO cell line retains normal morphology, pluripotency, and karyotype. This resource serves as a valuable tool for investigating ISL1′s function in cardiomyocyte differentiation.

通过基于附加型载体的 CRISPR/Cas9 系统生成 ISL1 纯合敲除干细胞系 (WAe009-A-1G)

ISL LIM 同源框 1 (ISL1) 基因属于 LIM/同源域转录因子家族,在传递心脏前体细胞的多能和增殖特性方面发挥着关键作用。 ISL1 突变与先天性心脏病有关。为了进一步探索ISL1在人类心脏中的作用,我们使用CRISPR/Cas9系统创建了纯合ISL1敲除(ISL1-KO)人类胚胎干细胞系。值得注意的是,该 ISL1-KO 细胞系保留了正常的形态、多能性和核型。该资源是研究 ISL1 在心肌细胞分化中的功能的宝贵工具。
