Abstract: Various implementations include systems and methods for automatically and continuously dissociating spheres of cells. In particular, one such system includes a peristaltic pump in fluid communication via tubing with a bioreactor in which cells are cultivated. A plurality of conduits are disposed within a portion of the tubing such that fluid flowing between the bioreactor and the pump passes through the conduits. The conduits have an inner diameter that is sized to provide a shear stress to the fluid of between about 5 to about 60 dynes/cm2, which is sufficient for dissociating the spheres of cells passing through the conduits. For example, each conduit may have an inner diameter of between about 50 and about 250 micrometers.

Abstract: Various implementations include systems and methods for automatically and continuously dissociating spheres of cells. In particular, one such system includes a peristaltic pump in fluid communication via tubing with a bioreactor in which cells are cultivated. A plurality of concentrically-arranged conduits are disposed within a portion of the tubing such that fluid flowing between the bioreactor and the pump passes through the conduits. The conduits have an inner diameter that is sized to provide a shear stress to the fluid of between about 5 to about 60 dynes/cm2, which is sufficient for dissociating the spheres of cells passing through the conduits.
