RESUMO
Red blood cell transfusion is an effective method to treat acute hemorrhage and severe anemia. However, blood source from donors is very limited, and transfusion-transmitted diseases occurred frequently, thus threatening human health. Therefore, the safe, abundant and functional blood source is needed. Generation of blood cells from human pluripotent stem cells(hPSC) will offer alternative approach. Lots of studies have been focused on erythroid cell differentiation in vitro, including how to enhance efficiency and improve their function. In this review, the research advances on differentiation methods and the regulatory mechanism are summarized. In addition, the progress in PSC differentiation into erythrocytes and the problems to be solved are discussed briefly.
