Human Leukocyte Antigen Class I and II Knockout Human Induced Pluripotent Stem Cell-Derived Cells: Universal Donor for Cell Therapy.

ABSTRACT: Background We aim to generate a line of "universal donor" human induced pluripotent stem cells (hi PSC s) that are nonimmunogenic and, therefore, can be used to derive cell products suitable for allogeneic transplantation. Methods and Results hi PSC s carrying knockout mutations for 2 key components (β2 microglobulin and class II major histocompatibility class transactivator) of major histocompatibility complexes I and II (ie, human leukocyte antigen [HLA] I/ II knockout hi PSC s) were generated using the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR associated protein 9 (Cas9) gene-editing system and differentiated into cardiomyocytes. Pluripotency-gene expression and telomerase activity in wild-type ( WT ) and HLAI / II knockout hi PSC s, cardiomyocyte marker
