Derivation of induced pluripotent stem cells line (RCPCMi007-A-1) with inactivation of the beta-2-microglobulin gene by CRISPR/Cas9 genome editing


The mismatch of HLA haplotypes between donor and recipient adversely affects the outcome of tissue transplantation. TheB2Mgene knockout (B2M-KO) disrupts the HLA I heterodimer formation; therefore,B2M-KO cells have reduced immunogenicity to allogeneic CD8+ T cells. Thus, theB2M-KO IPSCs and their derivatives can potentially solve a problem of the immunological compatibility in allogeneic transplantations. Using CRISPR/Cas9-mediated genome editing, we generated a human B2M-KO iPSC line (RCPCMi007-A-1). The RCPCMi007-A-1 iPSCs express pluripotency markers, have typical stem cell morphology, maintain normal karyotype, and the ability to differentiate into three germ layers.
