摘要:
Embodiments described herein generally relate to systems and methods for promoting the expansion of high density non-adherent cells through the use of a cell growth chamber, a mass transfer device, and a fluid circulation loop. Improved cell growth is achieved in the cell growth chamber by using a chamber having a particular orientation and shape, e.g., conical, to create a media-rich reservoir for growing cells. By placing the chamber in a vertical position, the force of media flow along the chamber walls is substantially equal and opposite to the gravitational force on the cells. The interaction of these forces maintains the non-adherent cells in suspension. The use of the cell growth chamber in conjunction with the mass transfer device and fluid circulation loop(s) creates efficiencies by relying on the cumulative and combined features of the devices.

A centrifugal blood separation system comprising a rotor, a light source, an optical sensor, a control system, a separation vessel, and an optical cell on the separation vessel. The optical cell has a first extraction port extending radially outwardly into the optical cell, a red blood cell extraction port downstream from the first extraction port and extending into the optical cell beyond the first extraction port; and a dam between said first extraction port and said red blood cell extraction port, having an upper edge and a lower edge, wherein the first extraction port and the red cell extraction port are radially between the upper edge and the lower edge of the dam. Also, a first extraction port having a bore having a first diameter, a lumen having a second diameter smaller than the first diameter, and a frustro-conical passageway coupling the bore to the lumen.

Embodiments described herein generally relate to methods and systems for configuring settings of a cell expansion system including a bioreactor. Through a user interface, a user may configure display settings, system settings, and settings associated with protocols for loading, growing and/or harvesting cells. In configuring settings for protocols and associated processes, a diagram view or window of the cell expansion system is displayed in embodiments. The diagram view displays the process settings as graphical user interface elements. Settings available for configuration are enabled for selection in the diagram view. The diagram view allows the user to visualize the settings available for task configuration and to configure enabled settings. Configured settings are stored and capable of retrieval for subsequent execution or modification of the applicable protocol.

摘要:
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, and outlet and a side tap outlet adjacent the inlet. The inlet may protrude into the cell separation chamber forming a circumferential well surrounding the protruding inlet. The side tap outlet may connect to the well. The set and system comprise means for selectively drawing fluid from either the outlet or the side tap outlet.
