The present invention relates to a novel bioreactor system for cell cultivation. More specifically, the invention relates to a compact bioreactor system which has several integrated functions and enables small scale static culture as well as scale-up rocking culture in the same bioreactor. The bioreactor system comprises tray for positioning of a cell culture bag having adjustable volume, a lid covering the cell culture bag and provided with heating function, an integrated perfusion unit, an integrated cell loading unit, and an integrated unit for automatic cell culture sampling, wherein the bioreactor system is controlled by a single control unit. The invention also relates to a method of cell culture using the bioreactor system for culture of therapeutic cells.

The present invention relates to a tissue cell culture device which includes a tissue cell culture body. The porous material used as the tissue cell culture body is a porous metallic material which is formed by pore cavities classified by a pore size of the material and cavity walls surrounding to form the classified pore cavities. The cavity wall surrounding to form an upper level of large pore cavity is provided with a lower level of small pore cavity. The pore cavities in the same level are in communication with each other. The pore cavities in different levels are also in communication with each other. This device is particularly beneficial for cell cultivation and allows tissue cells to grow freely and normally in a three-dimensional space.

Specialized culture plates for imaging cells in a quick, high throughput manner are provided. Ideally the wells of the culture plate have triangular, square, or V-shaped wells or cell sorting walls having a plurality of vertices, and more complicated variations thereof are also possible. The plates are tilted or rotated to collect the cells at the vertex or vertices of the wells, optionally vibrated to speed the collection, then the vibration and tilt or rotation removed for some period of time, whereon the cells are imaged through the flat transparent bottom of the plate.

An inflatable bioreactor (110, 210) may include one or more sheets joined to form a bag (111, 211) including a top sheet (118, 218) and a bottom sheet (119, 219) formed from the one or more sheets and being inflatable to provide an internal volume (117, 217) suitable for retaining a volume of culture liquid (10) during flow of the culture liquid resulting from a rocking motion (R) of the bag, and one or more perturbing protrusions (116, 116, 116, 216) extending upwardly from the bottom sheet toward, but not as far as, the top sheet and extending transversely to, or obliquely to, a direction of wave motion (W) of the culture liquid. The resulting construction may provide improved flow for low initial volumes of the culture liquid in the bag.

Disclosed is a cell culture incubator system having a sensor strip configured to be placed within a reaction vessel (e.g., incubator vessel) so as to position the sensor within media covering the cells. A reader is placed outside but adjacent the vessel to read the sensor so as to detect changes in dissolved O.sub.2 and pH. The system is used to determine if the incubator environment has too much CO.sub.2 and is therefore trending towards hypoxia and/or acidity, or has too much dissolved O.sub.2 and is therefore trending toward oxygen toxicity via the cell nutrient media. In some embodiments, the system includes a rocker unit configured to rock the reaction vessel to enhance cell growth. In some embodiments, the system includes a gas circulation system to adjust the CO.sub.2 and dissolved O.sub.2 levels in the reaction vessel.

The invention provides a full-automatic cell culture system, at least comprising: a control module, a control platform, a dark field microscope for on-line observation of cell culture, a cell incubator shaker and a cell culture bag. The control platform is connected to the dark field microscope for on-line observation of cell culture and the cell incubator shaker respectively, and the control module is connected to the control platform. The invention also provides a culture bag support frame for a continuous cell incubator shaker, the continuous cell incubator shaker, a non-contact sensor connector, the cell culture bag and the dark field microscope for on-line observation of cell culture which are related to the full-automatic cell culture system, thereby realizing continuous culture and observation of cells.

The invention discloses a modular quick-fit structure of an oscillating incubator, comprising: an incubator body, a combined mounting slot and an accessory mounting module. The combined mounting slot comprises a sliding slot body, a spring retainer is fixedly attached to a surface of one end of the sliding slot body; the accessory mounting module comprises a combined mounting plate, fixing grooves are provided at edges of two sides of the combined mounting plate, and an accessory module is fixedly installed over the combined mounting plate. The invention at least has the following beneficial effects that quick-fit and quick-connection between the combined mounting plate and the combined mounting slot facilitates the quick-fit and quick-connection between the accessory mounting module and the incubator body, so that problems of small space available for installation inside the machine and inconvenience to mount can be avoided.

The invention is an automated advanced tissue engineering system that comprises a housing in which one or more tissue engineering modules are accommodated together with a central microprocessor that controls functioning of the tissue engineering modules. In one embodiment, the tissue engineering module comprises a housing supporting one or more bioreactor chamber assemblies and a fluid reservoir operationally engageable with the housing. The bioreactor chamber assemblies may be selected depending on the end product option desired and may include, for example, a cell therapy bioreactor chamber, a single implant bioreactor chamber and a multiple (mosaic) implant bioreactor chamber.

Embodiments of a cell culture incubator system provided herein have two or more individual incubators and atmospheric regulation system configured to regulate atmospheric conditions within the environmental chamber of each individual incubator. The atmospheric regulation system has a single integrated controller system that controls atmospheric regulation of each of the individual incubators independently of the one or more other individual incubators. Atmospheric conditions within each of the individual incubators include at least the oxygen level and the total gas pressure, which are regulated independently of each other.
