Miniature Bioreactor System for Cell Culture

The miniature bioreactor system was developed to provide the capabilities for NASA to perform cell studies in space and then provide results back to investigators on Earth with minimal tools and cost. The miniature bioreactor system has the potential to also be used on Earth as a laboratory bench-top cell culturing system without the need for expensive equipment and reagents. The system can be operated under computer control to reduce the operator handling and to reduce result variations. The system includes a bioreactor, a fluid-handling subsystem, a chamber wherein the bioreactor is maintained in a controlled atmosphere and temperature, and control subsystems. The system can be used to culture both anchorage dependent and suspension cells (prokaryotic or eukaryotic cell types). Cells can be cultured for extended periods of time in this system, and samples of cells can be extracted and analyzed at specified intervals. The miniature bioreactor system for cell culturing has applications in pharmaceutical drug screening and cell culture studies.
