Generation of an induced pluripotent stem cell line MNDINSi001-A from a patient with neonatal diabetes caused by a heterozygous INS mutation

Abstract

Insulin gene (INS) mutations prove to be the second most common cause of permanent neonatal diabetes. Here, we report the generation of iPSC line from a patient, heterozygous for the intronic INS mutation that presumably leads to aberrant splicing. Dermal fibroblasts were reprogrammed using non-integrating RNA-based vector. Derivation and expansion of iPSCs were performed under feeder-free culture conditions. The iPSC line expressed pluripotency markers, had normal karyotype, could differentiate into three germ layers in vitro and retained the disease mutation. This line can be a powerful tool for modeling of diabetes and cell replacement therapy as well.
