Abstract
The method for the holding in flotation of a substance such as a tissue part in a bioreactor (61) is characterized in that the substance (73) is acted upon with a fluid; and in that the flow of the fluid acts counter to gravity in such a manner that the substance (73) is held in flotation. The bioreactor (61) with a container (62) for a substance (73) which is to be acted upon with fluid comprises a first flow chamber (66a) to which a flowing fluid can be supplied, with the first flow chamber (66a) being designed in such a manner that the fluid which flows upwardly therein has a lower speed with increasing height.
Claims38
A bioreactor comprising:
- a container comprising a first flow chamber;
- at least one scaffold having cells deposited on it for growing a tissue part, wherein the scaffold is acted upon with fluid;
- and
- an apparatus for conveying the fluid, wherein the scaffold is arranged in the first flow chamber in such a manner that the fluid holds the scaffold in free flotation.
A method for floating a scaffold for growing a tissue part, in a bioreactor, the method comprising:
- providing at least one scaffold having cells deposited on it;
- acting upon said scaffold with fluid, wherein the fluid holds the scaffold in free flotation and wherein
- the fluid flows in a direction counter to gravity when a density of said scaffold is greater then a density of the fluid, and in a direction counter to buoyancy when a density of said scaffold is less then a density of the fluid.
A method for floating a scaffold for growing a tissue part in a bioreactor, the method comprising:
- providing one or more tissue parts on at least one scaffold;
- and
- acting upon said scaffold and tissue parts with fluid, wherein the fluid holds the scaffold and tissue parts in free flotation and wherein
- the fluid flows in a direction counter to gravity when a density of said scaffold including tissue parts is greater then a density of the fluid, and in a direction counter to buoyancy when a density of said scaffold including tissue parts is less then a density of the fluid.
