Abstract
Genetically modified cells that are compatible with multiple subjects, e.g., universal donor cells, and methods of generating said genetic modified cells are provided herein. The universal donor cells comprise at least one genetic modification within or near a gene that encodes one or more MHC-I or MHC-II human leukocyte antigens or a component or a transcriptional regulator of a MHC-I or MHC-II complex, wherein genetic modification comprises an insertion of a polynucleotide encoding a tolerogenic factor and/or survival factor. The universal donor cells may further comprise at least one genetic modification within or near a gene that encodes a survival factor, wherein said genetic modification comprises an insertion of a polynucleotide encoding a second tolerogenic factor and/or a different survival factor.
