Embodiments are described that relate to methods and systems for growing cells in a hollow fiber bioreactor. In embodiments, the cells may be exposed to an activator for activating expansion of the cells. The cells may in embodiments include T cells, and the activator may be in different forms, including, for example, antigen presenting cells or beads functionalized with antibodies.

Embodiments described herein generally relate to passively replacing media in a closed cell expansion system to reduce or prevent the dilution of chemical signaling used to inhibit signaling pathways that keep a cell population in the lag phase of cell growth. To prevent such dilution, active inlet fluid flow to the system may be halted. To replace fluid lost by the system, a bag containing media may be attached to the waste line in replacement of the waste or outlet bag connected thereto. By turning off one or more pumps, media from the replacement bag is added to the system at the rate of evaporation. Chemical signaling dilution may be prevented while conserving system resources. Enhancement of chemical signaling to reduce the lag phase of cell growth may further be accomplished by adding molecules, such as chemical-signaling proteins, from a direct source to the system.

A method is provided in a centrifugal blood processing system for adding replacement fluid without a dedicated peristaltic pump to blood components being returned to the donor. A disposable blood processing set for use in the method comprises a hermetically sealed set of blood bags, connecting tubes, needles or connectors, and supporting structures with a replacement fluid line coupled directly to a return reservoir without contact with an intervening pump.

Embodiments relate to systems, chambers, and methods for processing particles by washing, concentrating, and/or treating the particles. Some embodiments provide for the processing of cells that may be in a liquid medium (e.g., a liquid in which the cells were grown) and are processed by being washed and concentrated for later use in research or other therapies.

Embodiments of a system box for holding a bag system and methods for separating composite liquids are described. In embodiments, a bag system may be a blood bag system used to collect blood, separate the blood into components, store the components, and utilize the components in patients. The system box may hold the blood bag system. Processes can then be performed to separate components from the blood.

Embodiments of methods and systems are described for automating protein production from genetically modified microorganisms. Embodiments provide for growing modified microorganisms to generate protein, releasing the protein and recovering the protein automatically. Also described are embodiments for lysing cells that may be used to as part of an automated system to recover the protein after generation by the microorganisms.

A disposable blood separation set and a centrifugal blood processing system comprising a blood processing chamber adapted to be mounted on a rotor of a centrifuge; a frustro-conical cell separation chamber in fluid communication with the processing chamber, the cell separation chamber having an inlet, a primary outlet and a side tap outlet adjacent the inlet. A valve that is responsive to centrifugal force (a gravity valve) selects between the outlet and the side tap outlet. The gravity valve is mounted on the rotor. When the rotor spins at high speed, the gravity valve may open the primary outlet and close the side tap outlet. When the rotor spins at a lower speed, the gravity valve may open the side tap outlet and close the primary outlet.
