    • Cells are cultured in a continuous culture system wherein glucose delivery and pH maintenance are based on values determined in a static culture of the cell line of interest. To provide maximum growth of the cell line in the continuous culture system, a pH level is maintained in the continuous culturing system corresponding to a pH value occurring at a point in time of greatest percentage increase in cell number in a static culture of the cell line of interest. The glucose and lactate levels are maintained in the continuous culture system corresponding to glucose and lactate levels at a point in time of greatest quantitative increase in cell number in the static culture of the cell line of interest. If the cell line of interest is a cell line used to produce a useful biological product, then the pH set point is changed at a maximum cell count to a value corresponding to a pH value occurring at a time wherein the cell count is at a maximum in the static culture and the glucose and lactate set points are changed to values corresponding to a point in time where the production of the biological product per cell per time period is greatest in the static culture.

    • A process mimics in-vivo or other conditions to a biological tissue that has been isolated from its natural nutrient supply by controlling the concentration of chemical stimuli delivered to the tissue. The process includes starting with a first known volume of the supportive media, having a known concentration of chemical stimuli affecting the tissue at an initial known point in time. Simultaneously, a first known volume and known amount of the chemical stimuli is removed from affecting the tissue and a second known amount of the chemical stimuli is added in a known volume having a known concentration different than the concentration of the chemical stimuli initially affecting the tissue. The volume of the supportive media is then determined along with the resulting concentrations of the chemical stimuli affecting the tissue. The above steps are repeated resulting in the concentration that affects the tissue being known at each and every point in time. In delivering the chemical stimuli to the tissue, the volume of the supportive media supplied to the tissue, the rate of delivery, rate of removal of the media along with the initial concentration of the chemical stimuli and the concentration of the chemical stimuli being supplied is used to determine a desired administration of the chemical stimuli such that the concentration affecting the tissue emulates the desired fluctuations of the chemical stimuli with respect to time. With these parameters defined, the concentration affecting the tissue with respect to time is known at each and every point in time. An apparatus for carrying out the above process is disclosed.

    • The invention relates to a pressure control system for an apparatus for cell cultivation and isolation of cell products (bioreactor), having a gas chamber (32) and having a cell culture chamber (26) located therein, as well as devices for gas introduction (64) and gas removal (66) which are connected to the apparatus, furthermore having devices (78) for introducing liquid nutrients and for removing liquid waste products (76), which are attached to the apparatus separate from the devices for gas introduction and gas removal. The means (68, 69) for controlling the gas pressure in the gas chamber (32) are functionally connected to the bioreactor in order to maintain a pressure in the cell culture chamber (26) which is higher than that in the gas chamber (32). In a second variant of the invention, the means (68, 82) for controlling the gas pressure in the cell culture chamber (26) are functionally connected to the bioreactor in order to maintain a pressure in the cell culture chamber (26) which is higher than that in the gas chamber (32). The devices for removing gas have a vacuum pump (69) and the devices for introducing liquid nutrients have a nutrient source (78) and pumps. The devices for removing liquid waste materials are provided with means (76) for collecting liquid materials, which are located underneath the apparatus so that syphon outflow is present.
