Objectives
Narrative objectives1
Airway epithelial cells are collected directly from patients with NTM-LD by bronchoscopy and analysed for lineage movement, etc., to elucidate the infection mechanism and patient background from the perspective of cell function on the host side. One problem with the analysis of airway epithelial cell function in clinical samples was the question of whether abnormalities in cell function (fibrillary motility) were the cause of NTM infection or the result of NTM infection, in a so-called 'chicken and egg' relationship.
Therefore, by reproducing airway epithelial cells from patients with NTM-LD in vitro using iPS cell technology from peripheral blood, functional evaluation was carried out in a system excluding acquired factors affecting airway epithelial cell function, such as infection on the host side or exposure to other smokes, and by comparing them with airway epithelial cells directly from the patient, Aiming to elucidate more essential mechanisms.

Primary outcomes
To determine the differences between the fibrillary motility of airway epithelium directly collected bronchoscopically from patients with NTM-LD and that of airway epithelium established from peripheral blood mononuclear cell-derived iPS cells collected from the same patients.
