Background: The novel ability to epigenetically reprogram somatic cells into induced pluripotent stem cells (iPSCs) through the exogenous expression of transcription promises to revolutionize the study of human diseases. Objective: Here we report on the generation of 25 iPSC lines from 6 patients with various forms of primary immunodeficiencies (PIDs) affecting adaptive immunity, innate immunity, or both. Methods: Patients' dermal fibroblasts were reprogrammed by expression of 4 transcription factors, octamer-binding transcription factor 4 (OCT4), sex determining region Y-box 2 (SOX2), Krueppel-like factor 4 (KLF4), and cellular myelomonocytosis proto-oncogene (cMYC), by using a single excisable polycistronic lentiviral vector. Results: iPSCs derived from patients with PIDs show a stemness profile that is comparable with that observed in human embryonic stem cells. After in vitro differentiation into embryoid bodies, pluripotency of the patient-derived iPSC lines was demonstrated by expression of genes characteristic of each of the 3 embryonic layers. We have confirmed the patient-specific origin of the iPSC lines and ascertained maintenance of karyotypic integrity. Conclusion: By providing a limitless source of diseased stem cells that can be differentiated into various cell types in vitro, the repository of iPSC lines from patients with PIDs represents a unique resource to investigate the pathophysiology of hematopoietic and extrahematopoietic manifestations of these diseases and might assist in the development of novel therapeutic approaches based on gene correction.
