A fluid mixing system includes a support housing having an interior surface bounding a chamber. A flexible bag is disposed within the chamber of the support housing, the flexible bag having an interior surface bounding a compartment. An impeller is disposed within the chamber of the flexible bag. A drive shaft is coupled with the impeller such that rotation of the drive shaft facilitates rotation of the impeller. A drive motor assembly is coupled with the draft shaft and is adapted to rotate the drive shaft. An adjustable arm assembly is coupled with the drive motor assembly and is adapted to move the drive motor assembly which in turn moves the position of the drive shaft and impeller. An electrical controller can control movement of the adjustable arm.

The invention provides a solution to the problem of transfecting non-adherent cells. Devices and delivery compositions containing ethanol and an isotonic salt solution are used for delivery of compounds and compositions to non-adherent cells.

A cell culture device includes: a culture tank of culturing a cell in a culture solution, the culture tank being in a shape in which a horizontal sectional area upwardly increases; a pump and a culture solution supply pipe, as a supply unit supplying the culture solution to the culture tank; and a control unit controlling the supply of the culture solution of the supply unit, in which the culture solution is intermittently supplied to the culture tank from the supply unit, according to the control of the control unit, and a circulation upward flow is formed in the culture solution, and thus, a plug flow of the culture solution is formed in a culture region in which the cell is retained in the culture tank.

One or more methods for treating a tissue site comprises collecting a tissue sample that has keratinoytes and placing the tissue sample in a cartridge that has a well plate, positioning the cartridge within a base unit that has a tissue disaggregator, activating the base unit to rotate the well plate to align wells in the well plate with the tissue sample and the tissue disaggregator, operate the tissue disaggregator to separate the tissue sample to form a regenerative epidermal suspension, and provide the regenerative epidermal suspension to a tissue site to enhance healing of the tissue site.

The present disclosure provides a membrane separation method of a cell suspension which can appropriately separate cells from debris, and a cell culture device. That is, membrane separation processing of the cell suspension is performed using a filtration membrane which includes an inlet-side opening formed on one surface and an outlet-side opening, which is formed on the other surface and communicates with the inlet-side opening, and in which the inlet-side opening and the outlet-side opening are disposed at positions deviated in a direction parallel to the surfaces of the membrane.
