OBJECTIVE@#To obtain skin-derived induced pluripotent stem cells (iPSCs) from an Osteogenesis imperfecta (OI) patient carrying WNT1c.677C>T mutation in order to provide a new cell model for investigating the underlying molecular mechanism and stem cell therapy for OI.@*METHODS@#The pathogenic variant of the patient was identified by Sanger sequencing. With informed consent from the patient, skin tissue was biopsied, and primary skin fibroblasts were cultured. Skin fibroblasts were induced into iPSCs using Sendai virus-mediated non-genomic integration reprogramming method. The iPSC cell lines were characterized for pluripotency, differentiation capacity, and karyotyping assay.@*RESULTS@#The patient was found to carry homozygous missense c.677C>T (p.Ser226Leu) mutation of the WNT1 gene. The established iPSC lines possessed self-renewal and capacity for in vitro differentiation. It also has a diploid karyotype (46,XX).@*CONCLUSION@#A patient-specific WNT1 gene mutation (WNT1c.677C>T) iPSC line was established, which can provide a cell model for the study of OI caused by the mutation.
