Genome editing in human stem cells.
The use of custom-engineered sequence-specific nucleases (including CRISPR/Cas9, ZFN, and TALEN) allows genetic changes in human cells to be easily made with much greater efficiency and precision than before. Engineered double-stranded DNA breaks can efficiently disrupt genes, or, with the right donor vector, engineer point mutations and gene insertions. However, a number of design consideratio...
متن کاملGenome Editing in Human Pluripotent Stem Cells.
Genome editing in human pluripotent stem cells (hPSCs) enables the generation of reporter lines and knockout cell lines. Zinc finger nucleases, transcription activator-like effector nucleases (TALENs), and CRISPR/Cas9 technology have recently increased the efficiency of proper gene editing by creating double strand breaks (DSB) at defined sequences in the human genome. These systems typically u...
متن کاملInduced Pluripotent Stem Cells Meet Genome Editing.
It is extremely rare for a single experiment to be so impactful and timely that it shapes and forecasts the experiments of the next decade. Here, we review how two such experiments-the generation of human induced pluripotent stem cells (iPSCs) and the development of CRISPR/Cas9 technology-have fundamentally reshaped our approach to biomedical research, stem cell biology, and human genetics. We ...
متن کاملSmall molecules enhance CRISPR genome editing in pluripotent stem cells.
The bacterial CRISPR-Cas9 system has emerged as an effective tool for sequence-specific gene knockout through non-homologous end joining (NHEJ), but it remains inefficient for precise editing of genome sequences. Here we develop a reporter-based screening approach for high-throughput identification of chemical compounds that can modulate precise genome editing through homology-directed repair (...
متن کاملRNA-programmed genome editing in human cells
Type II CRISPR immune systems in bacteria use a dual RNA-guided DNA endonuclease, Cas9, to cleave foreign DNA at specific sites. We show here that Cas9 assembles with hybrid guide RNAs in human cells and can induce the formation of double-strand DNA breaks (DSBs) at a site complementary to the guide RNA sequence in genomic DNA. This cleavage activity requires both Cas9 and the complementary bin...
