Method for inducing embryonic stem cells to be differentiated into erythroid cells in vitro

The invention discloses an effective method for inducing embryonic stem cells to be differentiated into erythroid cells in vitro. The embryonic stem cells are pre-induced through an inducing system containing dexamethasone, subjected to induction culture through a serum-free medium system containing a serum-free culture additive N2 or B27, prostaglandin E2 and L-glutamine, and then induced to be differentiated into the erythroid cells through a serum-free medium system containing stem cell factors (SCF), interleukin 3 and hemopoietin. The method specifically includes the following steps of conventionally culturing the embryonic stem cells in vitro, pre-inducing the embryonic stem cells, directionally differentiating the pre-induced cells into hematopoietic stem cells, and directionally differentiating the hematopoietic stem cells into the erythroid cells. According to the method for inducing the embryonic stem cells to be differentiated into the erythroid cells in vitro, materials are convenient to obtain, expansion in vitro is facilitated, immunogenicity is low, and therefore the human embryonic stem cells are differentiated into the mature erythroid cells more safely and efficiently, and the technological application prospects are good.
