Integration-free T cell-derived human induced pluripotent stem cells (iPSCs) from a patient with recessive dystrophic epidermolysis bullosa (RDEB) carrying two compound heterozygous mutations in the COL7A1 gene.

Expanded human T cells from a Japanese female with recessive dystrophic epidermolysis bullosa (RDBE) were used to generate integration-free induced pluripotent stem cells (iPSCs) by exogenous expression of four reprogramming factors, OCT3/4, SOX2, cMYC, KLF4, using Sendai virus vector (SeVdp). The authenticity of established iPSC line, RDEB-iPSC26, was confirmed by the expressions of stem cell markers and the differentiation capability into three germ layer. RDEB-iPSC26 may be a useful cell resource for the establishment of in vitro RDEB modeling and the study for developing gene and cell therapy.
