Abstract
The invention relates to an impeller for use in a bioreactor for growing adherent mammalian cells and/or a cell separator for adherent mammalian cells. The impeller of the invention is designed to efficiently and rapidly lift a bed of settled cells and microcarrier beads at low rotational speeds. Cell growth and concomitant yield is therefore improved by maintaining the culture in an environment of low shear force.
