Patent number: 4343904Abstract: Animal cells are grown in a vertically disposed cylindrical vessel containing a stack of parallel spaced-apart discs inclined at least 5.degree. from the horizontal and mounted to a rotatable axial shaft. The vessel is closed by a top plate having a plurality of inlets and a bottom plate with an outlet, and contains an external pumping loop for circulating contents of the vessel from the bottom to the top of the vessel. Growing of the cells is carried out by substantially filling the vessel with a mixture of animal cells and growth medium, allowing the cells to settle on the disc surfaces and then rotating the axial shaft at a speed of at least 5 rpm while continuously circulating the vessel contents from the bottom to the top of the vessel. This process and apparatus provides efficient mixing and ensures a homogeneous system within the vessel.Type: GrantFiled: August 21, 1980Date of Patent: August 10, 1982Assignee: G. D. Searle & Co.Inventors: John R. Birch, Terence Cartwright, John A. Ford
