Abstract: The present disclosure relates to a semipermeable membrane. The present disclosure aims to provide a semipermeable membrane having tolerance against a decrease over time in substance permeability. The present disclosure provides a semipermeable membrane (10) containing a resin. The permeation rate of albumin in the semipermeable membrane (10) is no lower than 30%. The albumin adsorption amount obtained when the semipermeable membrane (10) measuring 1 cm on each side is immersed in a 0.1% albumin solution for 90 minutes is no greater than 10 µg/cm 2 . The water permeation amount obtained when water is sucked through the semipermeable membrane (10) at a negative pressure of 3±0.2 kPa is expressed by no smaller than 1,000 L/(m 2 ·hour). The semipermeable membrane (10) can isolate a cell from an external environment.

Abstract: Provided is a simple method for producing a cell concentrate (other than human blood) in a short time with neither loss of cells nor an excessive burden on cells. Included is a method for producing a cell concentrate using an inside-out filtration system for processing a cell suspension, the system including: a cell suspension inlet port; a filtrate outlet port; a cell suspension outlet port; and hollow fiber separation membranes provided between the cell suspension inlet port and the cell suspension outlet port, wherein the membranes have a total cross-sectional area of 0.5-1.5 cm 2 , the membranes have an inside membrane area of 0.2 m 2 or less, the suspension is flowed inside the membranes at a linear velocity of 500-1200 cm/min, and the quotient of the division of the initial filtrate flow rate from the filtrate outlet port by the flow rate into the cell suspension inlet port is 0.4-0.7.
