However, the use of the affected tissue involves many issues; for example, sampling of the affected tissue may impose a severe burden on the patient or is sometimes technically impossible. Therefore, iPS cells are a powerful technology that can differentiate into the various tissues that make up our bodies. The aim of this study is to generate iPS cells from patients' and/or their family members' somatic cells and to use them together with clinical information to discover more about the cause of the diseases and to develop new effective treatments.\nTo elucidate the molecular mechanisms underlying the pathology of Primary Ciliary Dyskinesia (PCD) caused by disease-associated gene variants. To this end, we will establish patient-specific iPSCs and gene-corrected iPSC lines, differentiate them into airway epithelial cells, and perform single-cell RNA sequencing for comparative transcriptomic analysis."},"methods":{"ja":"【JGAS000617 / E-GEAD-623】フローサイトメトリーにより、誘導型2型肺胞上皮（iAT2）細胞（EpCAM+CPM+）と線維芽細胞（EpCAM-CPM-）を分離し、抽出したtotal RNAを用いたRNA-seq解析を実施した。\n【JGAS000846】ヒトiPS細胞由来の気道上皮細胞（疾患iPS細胞：PCD-iPSC、修復株：CCE1-iPSC）に対し、気液界面培養を用いて分化誘導後、scRNA-seqを実施した。","en":"[JGAS000617 / E-GEAD-623] Patient iPSC-derived type 2 alveolar epithelial (iAT2) cells (EpCAM+CPM+) and fibroblasts (EpCAM-CPM-) were isolated by fluorescence-activated cell sorting.
