Cells producing a desired product or products, such as antibodies, are cultured with a culture medium comprising lymph. The lymph is continuously flowed across a semi-permeable membrane (17), on the other side of which are the cells to be cultured. The membrane is sized so as to retain cells, and their desired products, on one - side of the membrane while permitting components of the lymph-containing culture medium (flowing across the other side of the membrane) to pass through the membrane to provide nutrition, etc. to the culturing cells. |
