  • Patent number: 9845455
    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.

  • Publication number: 20120156779
    Abstract: The present invention relates to a method for cell expansion. In the method, preferably a cell culture product is used, such as a microcarrier, or other adherent cell culture surface, comprising degradable polysaccharide, preferably starch, modified with small molecular weight cell-binding ligands. This allows recovery (detachment) of adhered cells to be aided by degradation of the culture surface with enzymatic agents, such as amylase. The method for cell expansion comprises the following steps: a) adding cells, culture medium and cell culture surface comprising a degradable polysaccharide with guanidine group containing ligands to a bioreactor; b) expanding said cells by adherent cell culture; and c) aiding the detachment of said cells by exposing them to a polysaccharidase to degrade the culturing surface.
