20110159584 | METHOD OF LOADING AND DISTRIBUTING CELLS IN A BIOREACTOR OF A CELL EXPANSION SYSTEM - A method of distributing a plurality of cells in a bioreactor of a cell expansion system includes manipulating an orientation of the bioreactor such that a net impulse due to gravity acting on the plurality cells in the bioreactor is reduced. One method includes (a) rotating the bioreactor at an angular velocity ω about an axis of rotation and through an angular displacement θ, the bioreactor rotating from a first orientation to a second orientation; (b) holding the bioreactor still at the second orientation for a first period of time t | 06-30-2011 |
20120088224 | Methods and Systems of Growing and Harvesting Cells in a Hollow Fiber Bioreactor System with Control Conditions - Embodiments described herein generally relate to methods and systems for using an air removal chamber as a control for a process in a cell expansion system. The air removal chamber may be mounted on a fluid conveyance assembly for use with the system. Fluid is pumped into a fluid containment chamber of the air removal chamber, in which the level of fluid in the fluid containment chamber may be monitored through the use of one or more sensors. The sensors are capable of detecting air, a lack of fluid, fluid, and/or a gas/fluid interface, e.g., an air/fluid interface, at measuring positions within the air removal chamber. Protocols for use with the system may include one or more stop conditions. In an embodiment, the stopping of a process is automated based on the detection of air, a lack of fluid, and/or a gas/fluid interface in the air removal chamber. | 04-12-2012 |
20140051162 | Method of Loading and Distributing Cells in a Bioreactor of a Cell Expansion System - One or more embodiments are described directed to a method and system for loading and distributing cells in a bioreactor of a cell expansion system. Accordingly, embodiments include methods and systems that may provide for adding a plurality of cells to a fluid within a bioreactor of the cell expansion system. A first percentage of the plurality of cells is avowed to settle in the bioreactor and a second percentage of the plurality of cells is allowed to settle outside of the bioreactor. The first percentage of cells is then expanded in the bioreactor. The second percentage of cells is wasted. | 02-20-2014 |

20150140654 | EXPANDING CELLS IN A BIOREACTOR - Described are embodiments for expanding cells in a bioreactor. In one embodiment, methods are provided that distribute cells throughout the bioreactor and attach cells to specific portions of a bioreactor to improve the expansion of the cells in the bioreactor. Embodiments may be implemented on a cell expansion system configured to load, distribute, attach and expand cells. | 05-21-2015 |
20150275170 | Passive Replacement of Media - 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. | 10-01-2015 |
