Abstract
The growth of cells within a device containing a bundle of semi-permeable, tubular capillaries is disclosed. The bundle of capillaries is wrapped in an envelope of porous sheet material, thus creating an extra-envelope space into which the cells can migrate for periodic removal without disturbing the main culture within the capillaries. Porous capillaries may also be employed, in place of or in addition to the porous envelope.
