| Outline of Final Research Achievements |
Chronic granulomatous disease (CGD) is a phagocyte disorder. It is also characterized by autoinflammation in the gastrointestinal (GI) tract, where innate lymphoid cells (ILCs) reside. Here, we clarified that the hematopoietic stem and progenitor cells, the origin of ILCs, in the CGD mice are comparable to wild-type control. Induced pluripotent stem (iPS) cells were generated from CGD patients. The human intestinal organoids (HIOs) were successfully generated from iPS cells. The resulting HIOs showed structures resembled normal morphology of human intestines and could be expanded more than 4 months suggesting the maintenance of the self-renewability of intestine stem cells. This is the first successful attempt at generating intestinal tissue from CGD-iPS cells. This is of importance due to the availability of patient’s samples and existing discrepancies between species. Here we established a new platform for studying human GI system in vitro and the pathophysiology of CGD colitis.
