Human pluripotent stem cells represent a powerful tool to study human embryonic development and disease but also open up novel strategies for cell replacement therapies. Their capacity to give rise to every cell type of the human body, meanwhile, enables researchers to generate high yields of mesodermal, ectodermal, but also endodermal-derived tissues such as hepatic, pancreatic, or intestinal cells. Another progress in the field came with the advent of 3-dimensional culture conditions, so-called organoids, which facilitate maturation of stem cells and in turn more faithfully recapitulate human tissue architecture. While several studies reported the derivation of organoid cultures from adult intestinal tissue, the derivation of intestinal organoids derived from plucked human hair of Crohn's disease patients has not been reported. The current research project reports such successful generation and characterization of induced pluripotent stem cells (iPSCs) derived from hair sheet keratinocyte cultures of a patient with Crohn's disease. Stepwise differentiation along the intestinal lineage showed no differences in intermediate stages such as definitive endoderm formation. We also directed the patterned primitive gut tube toward intestinal organoids resembling the cellular architecture of human "miniguts". As expected from current pathophysiological knowledge on Crohn's disease, there were no obvious morphological differences in the "miniguts" derived from healthy control and dis...
