Claim Text:
1. A method for removing predetermined cells from a body fluid, the method comprising: applying centrifugal force to the body fluid placed in a first bag by centrifugal separation to form separation layers having a concentration gradient of the predetermined cells, providing a force generating member that comprises: at least one of a centrifugal separator that produces the centrifugal force and a press that applies a pressure to the first bag; passing the separation layers through a filter in ascending order of the concentration of the predetermined cells according to the concentration gradient of the predetermined cells to remove the predetermined cells from the separation layers; and receiving the separation layers from which the predetermined cells have been removed in a second bag; wherein, when the separation layers are passed through the filter, one of the centrifugal force and the pressure generated by the force generating member is changed so as to regulate and change a passing rate of each of the separation layers being passed through the filter according to a concentration of the predetermined cells in the separation layers having the concentration gradient of the predetermined cells.
