CD55 and paroxysmal nocturnal hemoglobinuria: After hematopoietic induction, the differentiated cells from PNH fibroblast-iPSCs expressed early hematopoietic markers (CD34 and CD43) with normal CD55 and CD59 expression similar to those of their parental cells, suggesting that PNH fibroblast-iPSCs can be a potential source of HSCs for autologous transplantation to cure PNH patients.
