Abstract
Official abstract text for this publication.
A method of modulating some or all copies of a gene in a cell is provided including introducing into a cell one or more ribonucleic acid (RNA) sequences that comprise a portion that is complementary to all or a portion of each of the one or more target nucleic acid sequences, and a nucleic acid sequence that encodes a Cas protein and maintaining the cells under conditions in which the Cas protein is expressed and the Cas protein binds and modulates the one or more target nucleic acid sequences in the cell.
First claim
Opening claim text (preview).
What is claimed is: 1. An isolated porcine organ comprising a plurality of genetically engineered porcine cells, wherein each genetically engineered porcine cell of said plurality is characterized in that at least 97% of the porcine endogenous retrovirus (PERV) pol genes comprise a genetically engineered genomic indel. 2. The organ of claim 1 , wherein 100% of the PERV pol genes comprise a genetically engineered genomic indel. 3. The organ of claim 1 , wherein each genetically engineered porcine cell exhibits at least a 1000-fold reduction in PERV transmission as evidenced by co-culturing a human cell with the genetically engineered porcine cell as compared to co-culturing a human cell with a wild-type porcine cell. 4. The organ of claim 3 , wherein the human cell is HEK293. 5. The organ of claim 1 , wherein the genetically engineered genomic indel is observed by sequencing. 6. The organ of claim 1 , wherein the individual genetically engineered porcine cell contains intact PERV gag and/or env genes.
