Abstract: The present invention relates to a method for cell expansion. More closely, it relates to a method for expansion of cells, such as mesenchymal stem cells, on microcarriers in a plastic bag bioreactor. The invention enables expansion to therapeutic amounts of stem cells. The method comprises the following steps: a) addition of cells in cell culture medium and microcarriers to a plastic bag container; b) allowing the cells to adhere to the microcarriers while the container is kept substantially still; c) addition of further cell culture medium once the cells have adhered; d) culturing the cells under gentle and constant agitation; e) increase the surface area for continued culturing; and f) final harvesting of cells by an active detachment and separation step.

Abstract: An inflatable bioreactor bag for cell cultivation, which comprising a top and a bottom sheet of flexible material, joined together to form two end edges and two side edges, wherein one baffle or a plurality of baffles extend from the bottom sheet in a region where the shortest distance to any one of the two end edges is higher than about one fourth of the shortest distance between the two end edges.

Abstract: A method of cultivating cells in a bag is disclosed, which comprises the steps of: a) providing a sterile flexible bag comprising a filter material which is attached to a wall of the culture bag, wherein the filter material delimits a chamber inside the bag and wherein the chamber is fluidically connected to a first port in a wall of the bag, b) providing agitation means for the bag, c) introducing cell culture medium, microcarriers and cells to the bag, d) cultivating cells in the bag with agitation provided by the agitation means, allowing formation of a suspension of microcarriers with immobilized cells and supplying at least one gas via a second port (not shown) in a wall of the bag, e) removing cell debris and/or free cells together with liquid from said suspension of microcarriers through the filter material and the first port.

Abstract: The present invention relates to the field of adherent cell culture. More closely, the invention relates to a method for production of a cell attachment and culture surface, such as a microcarrier, comprising a guanidino-containing ligand, wherein the ligand is coupled via reaction involving a primary amine to the surface which is activated by activation groups such that the final molar ratio of grafted ligand and ungrafted activation groups is above 1.5. Preferably, the ligand density is above 0.5 mmol/g cell culture surface and the remaining activation groups after coupling is less than 0.6 mmol/g cell culture surface. The cell culture surface may be used for various purposes, primarily cell cultivation and virus production.
