مستخلص: | A bioreactor system features a vessel capable of being temperature controlled comprised of two or more cylindrical chambers separated by a common porous membrane. The chambers are capable of being mounted for rotation about a common horizontal axis, essentially creating a micro gravity environment, for the purpose of creating an interface between the chambers while maintaining fluid culture medium in at least one of the chambers and enabling cells to grow in the wells or pores disposed between the chambers. The device is formed by a tubular vessel having an inner surface and an outer surface, a first open end, a second open end and a longitudinal axis. |
