To address basic cell biology questions such as “Can cells respond to a gravity stimulus?”, a Cell Culture Unit (CCU) is being developed for use in the International Space Station. The CCU will accommodate diverse specimen types (animal, plant, and microbial cells; tissues; aquatic organisms) in up to twenty-four cell specimen chambers. The environmental conditions (e.g. temperature, pH, gas concentrations) will be maintained by medium recirculation and renewal, and gas and heat exchange. The CCU will also provide for the addition of experimental agents (e.g. growth factors), automated sampling, and monitoring of the specimens by video microscopy. Microgravity experiments will be performed using the CCU within the Habitat Holding Rack (HHR); a CCU within the Space Station Centrifuge will serve as an on-board unit-gravity control.
