Abstract: The present invention relates to a method for in vitro production of red blood cells. The method for in vitro production of red blood cells, according to the present invention, specifies, by cell size, the maturation step of cells exhibiting optimal effects in an agitation-type culture, so that even if an expert does not always identify cell shape, automated processes of culturing are possible, and thus automation in bioreactors is possible in the mass-production of uniform quality and red blood cells.
