Modes of stem cell therapy. A Autologous transplantation with the patient’s own induced pluripotent stem cells (iPSCs). B Allogeneic transplantation with iPSCs from healthy donors or human embryonic stem cells without HLA-haplotype matching. C Allogeneic transplantation with HLA-matching iPSCs. D Allogeneic transplantation with “universal cells” that are genetically edited to knock down HLA molecules
