Definitions
- Bioreactor and adherent cell culture production procedure using the bioreactor are Bioreactor and adherent cell culture production procedure using the bioreactor.
- the present invention refers to a bioreactor (also called a Kruter), of special application in biochemical processes in which cellular or microbial systems are used for the production of biological products. It also refers to a method of producing adherent cell cultures, especially for the formation of tissues and cultured meat, which uses said bioreactor.
- Bioreactors have multiple applications, such as the food and fermentation industries, waste treatment, and many biomedical facilities.
- a heater is a tank within which organic reactions are carried out, providing a suitable environment for various microorganisms under the required conditions. It must allow controlling the temperature by heat or cold, controlling the pH, aeration ranges, nutrient content, etc.
- a bioreactor is a container in which a chemical process is carried out that involves organisms or biochemically active substances derived from said organisms. This process can be aerobic or anaerobic.
- These bioreactors are commonly cylindrical, ranging in size from a few milliliters to cubic meters, and are usually made of stainless steel.
- a bioreactor can also be a device or system used to grow cells or tissues in cell culture operations. These devices are under development for use in tissue engineering. In general terms, a bioreactor seeks to maintain certain favorable environmental conditions (pH, temperature, oxygen concentration, etc.) for the organism or chemical being grown.
- the types of heaters available on the market have a number of common components and characteristics: the tank must be designed to work aseptically for many days with minimal energy consumption
- bioreactors are widely used for the cultivation of microorganisms (bacteria, fungi, cells, etc.), both on a laboratory scale and on an industrial scale. Its design is normally a tank stirred by mechanical devices, either by rotating blades or by column bubbling. And the cultures of microorganisms in suspension are carried out.
- Cell suspensions consist of free cells and cell aggregates distributed in a moving medium.
- Another example is the iCELLis® bioreactor, a fixed bed system for the growth of adherent cells.
- the object of the present invention is, therefore, to provide a bioreactor that allows adherent cells to be grown simply and efficiently, so that it is productive on a large scale, especially for the production of tissue and cultured meat.
- the invention provides a bioreactor, comprising a container with a lid, and further comprising a support inside which protrudes at least one tray that supports a three-dimensional polymer-based element located thereon, such that when the bioreactor is filling with the culture medium the at least one tray and the polymer-based three-dimensional element are surrounded by the culture medium.
- the invention also provides a method of producing adherent cell cultures, which employs said bioreactor, and which comprises the following steps:
- the cells to be sown are inoculated onto the polymer-based three-dimensional element, and - the culture is left in the bioreactor so that cell proliferation occurs.
- the configuration of the bioreactor allows proliferated adherent cells to achieve their functions of extracellular matrix growth and tissue formation in a way more similar to the processes performed in vivo, and making the corresponding procedure more productive. In this way, the tissues formed have a high protein value.
- Figure 1 shows a view of a bioreactor of the invention showing the support and the trays.
- Figure 2 shows the assembly formed by the support, the trays, the rings and the polymer-based three-dimensional elements of the bioreactor of the invention.
- Figure 3 shows the assembly of figure 2, to which air bubble generators have been added under each tray.
- FIG 1 shows a view of a bioreactor 1 of the invention obtained from a commercial or traditional bioreactor.
- the conventional bioreactor comprises a container 2 with a lid 3.
- a support 4 has also been included inside it, in which trays 5 can be placed.
- the bioreactor 1 has three trays 5, which can be made of stainless steel. The number of trays 5 can increase or decrease depending on the needs and size of the bioreactor 1.
- each tray 5 supports a three-dimensional element 6 with a polymeric base located on it, that is to say, these trays 5 suppose support places for three-dimensional elements 6 (three-dimensional matrices) that act as growth "scaffolds" for adherent cells.
- These “scaffolds” can be hydrogel-type polymer-based three-dimensional structures 6, on which the cells can be seeded by inoculation from outside the bioreactor 1 with a needle and leave in culture until the proliferation achieved is the desired one.
- the trays 5 and the polymer-based three-dimensional elements 6 are surrounded by the culture medium.
- the support 4 can be suspended from the lid 3 of the bioreactor 1, in such a way that once the bioreactor 1 is closed, the trays 5 and the three-dimensional elements 6 of polymer base are submerged in the culture medium.
- the support 4 can protrude perpendicularly from the cover 3.
- the support 4 can also be supported on the base of the bioreactor 1 independent of the cover
- the trays 5 can be drilled through a series of through holes, to allow a better flow of liquid throughout the bioreactor 1.
- the bioreactor 1 can include rings 7 for holding the polymer-based three-dimensional elements 6 ("scaffolds"), which also protrude from the support 4 in a parallel position with respect to a corresponding tray 5, so that the polymer-based three-dimensional element 6 is located between the corresponding tray 5 and the corresponding ring 7.
- sinaffolds polymer-based three-dimensional elements 6
- the support 4 can include several profiles or support rods on which the trays 5 and rings 7 rest. On these profiles it is possible to include electrical contacts 8 capable of being supplied with direct or alternating current. This direct or alternating current, which can be of the order of microamps, facilitates and increases cell proliferation.
- the bioreactor 1 may also additionally include an air bubble generator 9 under each tray 5.
- the cell culture production procedure, which employs a bioreactor 1, comprises the following steps:
- the support 4 with the at least one tray 5 of the bioreactor 1 with the polymer-based three-dimensional element 6 is immersed in the culture medium, - the cells to be sown on the three-dimensional element 6 are inoculated from the outside of the bioreactor 1 polymer-based, and
- Said procedure may additionally comprise a step of stimulating cell proliferation consisting of supplying the electrical contacts 8 of the support 4 of the bioreactor 1 with direct or alternating current.
- said method may additionally comprise a cell proliferation stimulation step consisting of producing air bubbles under each tray 5 by means of the air bubble generators 9.
- the invention is of special application to the cultivation of animal muscle cells for the production of cultured meat, but it is not only limited to this application or to this type of adherent cells.
