Abstract

Embodiments described herein generally provide for the scheduled feeding of cells in a cell expansion system. A schedule to proactively and automatically increase and/or maintain inlet rates of media to feed cells may be created, in which inlet rates to the intracapillary portion (or extracapillary portion) of a bioreactor may be increased or maintained according to the schedule. Such schedule may be conservative or aggressive or a combination thereof, for example. Multiple schedules may be used. Scheduled media exchanges may also be included. By following a feed schedule, the monitoring of metabolite levels may be optional. Inlet rates may be increased or maintained without manual manipulation. Media usage may also be more predictable. In an embodiment, a custom task(s) may be created to follow a desired feed schedule. In another embodiment, a pre-programmed task(s) may be used for the scheduled feeding of cells.
