Generation and characterization of a human induced pluripotent stem cell line heterozygous for a NOTCH1 mutation (NCHi014-A)

NOTCH1 signaling is crucial for cardiovascular development. Numerous studies have identified heterozygous NOTCH1 loss of function and missense variants associated with a spectrum of congenital heart diseases (CHD). We generated induced pluripotent stem cells (iPSC) from a healthy individual to develop a model for NOTCH1+/-iPSC to study the molecular pathogenesis of CHD. NOTCH1+/-iPSC (NCHi014-A) have normal morphology and karyotype, are identical to the parental cell line, express pluripotency markers and have the ability to differentiate to the three germ layers. NOTCH1+/-iPSC can be used as a tool to study the cellular and molecular mechanisms underlying NOTCH1-associated human CHD.
