Patent number: 8975072Abstract: Provided are: a method for producing an immortalized human erythroid progenitor cell line, enabling efficient and stable production of enucleated red blood cells; and a method for producing human enucleated red blood cells from a human erythroid progenitor cell line obtained by the aforementioned production method. An expression cassette capable of inducing expression of HPV-E6/E7 genes in the presence of DOX was introduced into the genomic DNA of blood stem cells. Then, the blood stem cells were cultured in the presence of DOX and a blood growth factor. Thereby, immortalized cell lines of human erythroid progenitor cells were established. Further, it was revealed that culturing the cell lines under a condition where the expression of the HPV-E6/E7 genes was not induced enabled differentiation induction into enucleated red blood cells at a high ratio.Type: GrantFiled: January 18, 2013Date of Patent: March 10, 2015Assignee: RikenInventors: Yukio Nakamura, Ryo Kurita
