Abstract

279. Derivation and Functional Analysis of Patient Specific Induced Pluripotent Stem Cells as an In Vitro Model of Chronic Granulomatous Disease

Highlights

  • Chronic granulomatous disease (CGD) is an inherited disorder of phagocytes in which NADPH oxidase is defective in generating reactive oxygen species

  • Autologous hematopoietic stem cell (HSC) gene therapy represents an alternative to allogenic bone marrow transplantation (ABMT)

  • We showed that reprogramming vector-free induced pluripotent stem cells (iPSC) clones continue to express pluripotent markers and are able to form embryoid bodies in vitro and teratomas in immunodeficient mice

Summary

Introduction

Chronic granulomatous disease (CGD) is an inherited disorder of phagocytes in which NADPH oxidase is defective in generating reactive oxygen species. Autologous hematopoietic stem cell (HSC) gene therapy represents an alternative to ABMT. Over the last few years, researchers were able to generate induced pluripotent stem cells (iPSCs) by reprogramming differentiated cells with retroviral expression of stem cell factors (Oct3/4, Sox2, Klf4 and c-Myc).
