Аннотация
Ventricular septal defect (VSD) is one of the common congenital heart malformations. Several factors lead to the development of VSD, including familial causes, exposure to certain drugs, infectious agents, and maternal metabolic disturbances. We considered that induced pluripotent stem (iPS) cells derived from VSD patients can be used to study the origin and pathogenesis of the VSD. Here, we show generation and cardiomyocyte differentiation potential of iPS cells from thymic epithelial cells of a patient with VSD (TECs-VSD) by overexpressing the four factors: OCT4, SOX2, NANOG, and LIN28 with lentiviral vectors. The self-renewal and pluripotency of the VSD-iPS cells was verified in iPS cells by in vitro expression of pluripotency markers and formation of teratoma in vivo. iPS cell lines from VSD patients differentiated into functional cardiomyocytes can serve as a model system for studying the pathophysiology and identifying etiology of VSD.
