Flexible bioreactor for therapeutic cells

摘要

A flat flexible container forms a bioreactor for cell cultivation. The relatively small volume cell compartment is defined between a gas-permeable outer wall and a semipermeable membrane while the large volume compartment for the culture medium is defined between the semipermeable membrane and another gas-permeable outer wall. Oxygen is supplied from the exterior and outwardly diffusing carbon dioxide is removed. <IMAGE>
