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: A double-walled-structure, such as a silencer for use in a ventilation duct system, has a perforated inner tube, an outer casing which is arranged at a distance from the inner tube and encloses the same, and a tubular, sound-absorbing element which is arranged between the inner tube and the casing. The tubular element has an increasing density radially outwards from the center axis of the inner tube. The silencer is produced by the sound-absorbing element being arranged on the inner tube, and the inner tube with the sound-absorbing element arranged thereon being enclosed in the surrounding outer casing.
