HLA DR Genome Editing with TALENs in Human iPSCs Produced Immune-Tolerant Dendritic Cells

Figure 5

Validation of HLA DR knockout iPSC immunogenicity. CD83-positive matured DC from HLA DR knockout iPSCs does not express HLA DR, and there is no response to the CD4 T cells. (a) FACS analysis showed the expression of CD83 and HLA DR for wild-type iPSC-derived DC vs. HLA DR knockout iPSC-derived DC. (b) MLR assay revealed that wild-type iPSC-derived DC significantly induced allogeneic lymphocyte activation compared with HLA DR knockout iPSC-derived DC.
