Abstract

Genetically modified cells that are compatible with multiple subjects, e.g., universal donor cells, and methods of generating the genetically modified cells are provided herein. The universal donor cells comprise at least one genetic modification within or near at least one gene that encodes one or more MHC-I or MHC-II human leukocyte antigens or component or transcriptional regulator of the MHC-I or MHC-II complex, at least one genetic modification that increases the expression of at least one polynucleotide that encodes a tolerogenic factor, and optionally at least one genetic modification that increases or decreases the expression of at least one gene that encodes a survival factor.
