    摘要: A method for culturing cells includes introducing cells within an extracapillary space defined by a shell (12) and a plurality of hollow semi-permeable fibers (22) extending therethrough. The semi-permeable fibers are spaced from each other a distance substantially similar to a distance that tissue capillaries are spaced from each other in in vivo living tissue. Media is passed through the hollow fibers and cell growth having a density substantially equal to that of in vivo living tissue is observed.

    摘要: Un dispositif amélioré de culture de cellules comprend une cartouche de fibres creuses (11) ayant une coquille (16) et une pluralité de capillaires (12) s'étendant au travers de la coquille, au moins certains de ces capillaires (12) ayant des parois sélectivement perméables. Un espace de culture de cellules (14) est défini entre la coquille (16) et les capillaires (12). L'amélioration comprend une chambre (32) contenant une seconde alimentation (33) en connexion fluide avec l'espace de culture de cellules. Un système de pressurisation (46) met sous pression le milieu d'alimentatin dans la chambre jusqu'à un niveau supérieur au niveau du milieu s'écoulant au travers du passage des capillaires. Un mécanisme à soupape (38, 40) restraint alternativement et sélectivement l'écoulement du milieu entre la chambre et les conduits de sorte que la circulation s'effectue dans l'espace de culture de cellules (14).

    摘要: An improved cell culturing device includes a hollow fiber cartridge (11) having a shell (16) and a plurality of capillaries (12) extending through the shell with at least some of the capillaries (12) having selectively permeable walls. A cell culturing space (14) is located between the shell (16) and capillaries (12). The improvement includes a chamber (32) containing a second medium supply (33) fluidly connected to the cell culturing space. A pressurizing system (46) pressurizes the medium within the chamber to a level higher than the level of medium flowing through the lumen of the capillaries. A valving mechanism (38, 40) alternatively and selectively restricts flow of medium between the chamber and the conduits such that circulation is effected in the cell culturing space (14).

    摘要: Un dispositif de culture à fibres creuses comprend une première cartouche de fibres creuses (12) et une seconde cartouche de fibres creuses (14), dont les capillaires (18) sont connectés en série par une connexion fluide (36) ayant à l'intérieur un étranglement d'écoulement (38). L'étranglement d'écoulement (38) établit une chute de pression entre les capillaires de la première (18) et de la seconde (28) cartouches et établit une contre-pression sur les capillaires de la première cartouche de fibres creuses de sorte que le milieu est administré par perfusion dans des conditions d'ultrafiltration. L'espace extracapillaire (34) de la première cartouche de fibres creuses est connecté par des moyens fluides à l'espace extracapillaire de la seconde cartouche de fibres creuses (14) de sorte que le milieu contenant le déchet et le produit est acheminé vers l'espace extracapillaire (34) de la seconde cartouche de fibres creuses où le produit est concentré et le milieu contenant le déchet est diffusé dans le passage des capillaires.

    摘要: A cell culture device includes at least one bioreactor (50) having at least one semi-permeable membrane defining first and second chambers on opposite sides of the membrane. A first circuit (54) is provided for circulating a media including nutrients and the like through the first chamber and a second circuit (72) is provided for circulating a second fluid for cell culture through the second chamber of the bioreactor (50). A plurality of bioreactors (50) may be connected in parallel in the first and second circuits (54, 72) and provision is made for balancing the flow in each reactor. The flow in the second circuit (72) can be periodically reversed to provide increased cell culture.

    摘要: A method of culturing cells by providing a highly gassed media on a continous basis to cells grown in a hollow fiber cartridge includes entraining the media with gas above the gas solubility level of the media. The media is then permitted to rest in a substantially quiescent state so that non-solubilized gas leaves the media. The media is then pressurized prior to delivery to the hollow fibers sufficiently so that the pressure drop and/or flow disturbance in the cell culturing device does not decrease the gas solubility level of the media below the media's gas saturation point.
