| Research Abstract |
Although previous reports describe that the activation of vascular endothelial cells is involved in the development of vascular inflammation in animal models, the disease mechanisms of vasculitis remain largely unknown in human. Here, we report the derivation of induced pluripotent stem cells (iPSCs) from skin fibroblasts of three patients with MPA by retroviral transduction of four transcription factors or three factors. The gene expression of endothelial cells derived from human iPSCs was compared between MPA patients and healthy individuals using DNA microarray. In the endothelial cells derived from MPA patients, the expression of 41 genes was up-regulated and the expression of 91 genes was down-regulated by 2-fold compared with healthy individuals.
