Abstract

Our group generated two induced pluripotent stem cell (iPSC) lines for in vitro red blood cell (RBC) production from blood donors with extensively known erythrocyte antigen profiles. One line was intended to give rise to RBCs for transfusions in patients with sickle cell disease (SCD), while the other was developed to create RBC panel reagents. Two blood donors were selected based on their RBC phenotypes, further complemented by high-throughput DNA array analysis to obtain a more comprehensive erythrocyte antigen profile. Enriched erythroblast populations from the donors' peripheral blood mononuclear cells were reprogrammed into iPSCs using nonintegrative plasmid vectors. The iPSC lines were characterized and subsequently subjected to hematopoietic differentiation. iPSC PB02 and iPSC PB12 demonstrated in vitro and in vivo iPSC features and retained the genotype of each blood donor's RBC antigen profile. Colony-forming cell assays confirmed that iPSC PB02 and iPSC PB12 generated hematopoietic progenitors. These two iPSC lines were generated with defined erythrocyte antigen profiles, self-renewal capacity, and hematopoietic differentiation potential. With improvements in hematopoietic differentiation, these cells could potentially be more efficiently differentiated into RBCs in the future. They could serve as a complementary approach for obtaining donor-independent RBCs and addressing specific demands for blood transfusions.
