Molecular Imaging of Human Embryonic Stem Cells Stably Expressing Human PET Reporter Genes After Zinc Finger Nuclease-Mediated Genome Editing Hasselt University KU Leuven
Molecular imaging is indispensable for determining the fate and persistence of engrafted stem cells. Standard strategies for transgene induction involve the use of viral vectors prone to silencing and insertional mutagenesis or the use of nonhuman genes. Methods: We used zinc finger nucleases to induce stable expression of human imaging reporter genes into the safe-harbor locus adeno-associated virus integration site 1 in human embryonic stem ...
Haemophilia gene therapy Vrije Universiteit Brussel KU Leuven
Haemophilia is an attractive disease target for gene therapy that fostered the development of the field at large. The delivery of the clotting factor genes into the patients' cells could be accomplished using different types of gene delivery vehicles or vectors. Adeno-associated viral vectors (AAV) and lentiviral vectors represent some of the most promising gene delivery technologies that allow for a relatively efficient delivery of the ...
Chromatin structure of two genomic sites for targeted transgene integration in induced pluripotent stem cells and hematopoietic stem cells Vrije Universiteit Brussel
Achieving transgene integration into preselected genomic sites is currently one of the central tasks in stem cell gene therapy. A strategy to mediate such targeted integration involves site-specific endonucleases. Two genomic sites within the MBS85 and chemokine (C-C motif) receptor 5 (CCR5) genes (AAVS1 and CCR5 zinc-finger nuclease (CCR5-ZFN) sites, respectively) have recently been suggested as potential target regions for integration as ...
The human somatostatin receptor type 2 as an imaging and suicide reporter gene for pluripotent stem cell-derived therapy of myocardial infarction Hasselt University KU Leuven
Rationale: Pluripotent stem cells (PSCs) are being investigated as a cell source for regenerative medicine since they provide an infinitive pool of cells that are able to differentiate towards every cell type of the body. One possible therapeutic application involves the use of these cells to treat myocardial infarction (MI), a condition where billions of cardiomyocytes (CMs) are lost. Although several protocols have been developed to ...
Strategies for In Vivo Genome Editing in Nondividing Cells KU Leuven
Programmable nucleases, including zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9), have enhanced our ability to edit genomes by the sequence-specific generation of double-strand breaks (DSBs) with subsequent homology-directed repair (HDR) of the DSB. However, the efficiency of the HDR pathway is limited in ...
Gene editing technology for improving life quality: A dream coming true? KU Leuven
The fact that monogenic diseases are related to mutations in one specific gene, make gene correction one of the promising strategies in the future to treat genetic diseases or alleviate their symptoms. From this perspective, and along with recent advances in technology, genome editing tools have gained momentum and developed fast. In fact, clustered regularly interspaced short palindromic repeats-associated protein 9 (CRISPR/Cas9), transcription ...
Doelgerichte aanpassing van het PSIP1 gen coderend voor LEDGF/p75 beschermt cellen tegen HIV infectie. KU Leuven
Gene therapy has long held promise to correct a variety of human diseases. Discovery of the Clustered Regularly-Interspaced Short Palindromic Repeats (CRISPR), the mechanism of the CRISPR-based prokaryotic adaptive immune system (CRISPR-associated system, Cas) and its repurposing into a potent gene editing tool has revolutionized the field of molecular biology and generated excitement for new and improved gene therapies. Additionally, the ...
