The present invention is a first step of obtaining a cell group comprising a CD34 negative cell that culminates a cell group of primate animal pluripotent stem cells under conditions suitable for induction of differentiation into hematopoietic cells, and at least a portion of the cell group obtained in the first step described above The hematopoietic system of primates is characterized by having a second step of transplanting into an animal of a different animal, and a third step for obtaining the hematopoietic cells of the primate from the body of the animal obtained by raising the baby obtained from birth CystThe present invention relates to a manufacturing method.本発明は、霊長類動物の多能性幹細胞の細胞群を、造血系細胞への分化誘導に適した条件で培養する、CD34陰性細胞が含まれる細胞群を得る第一工程と、前記第一工程で得た細胞群の少なくとも一部を前記霊長類動物とは異なる動物の胎仔に移植する第二工程と、前記胎仔が出生に至って得られた仔動物を育成させて得た動物の体内から前記霊長類動物の造血系細胞を得る第三工程と、を有することを特徴とする、霊長類動物の造血系細胞の作製方法に関する。
