Permanent repair of the F9 gene is a significant goal to cure Hemophilia B disease. Advanced gene therapy using CRISPR/Cas9 system can increase circulation level of Factor IX proteins to a significant level without the need of demanding infusions of FIX concentrates. Induced pluripotent stem cells represent an ideal cell for gene therapy because patient-derived cells could be reprogrammed into iPSCs, genetically modified, selected, expanded and then induced to differentiate into fully functional hepatocytes in vitro. This study covered a portion of a 5-year project which ultimately aims at establishing therapeutic results in transgenic Hemophilia B mice by injecting genetically corrected iPSC-derived hepatocytes into the liver. The purpose of this thesis is to summarize what has been completed up to now: generation of the proper model of Hemophilia B human iPSCs using CRISPR/Cas9-mediated genome editing and differentiation of healthy and disease specific iPSCs into hepatocytes which will allow disease modelling to look for cell function, viability, homogeneity and drug screening. Further research will be done to effectively knock-in the F9 allele into liver safe harbor site of disease specific iPSCs, which will express FIX at a significant level to show therapeutic effects.
