T-CGS is unique hardware that is being newly utilized for microgravity research.
- The T-Cell Growth System (T-CGS) is designed to maintain cell cultures in a 2-dimensional petri dish by providing nutrients in a controlled fashion and a growth substrate in microgravity.
- The growth nutrients are transferred via a wick to a growth substrate using a novel silica tile material. The units are designed to be maintained at 37 degrees C and to contain a 5% carbon dioxide/air combination environment through the use of non-permeable seals and material.
The T-CGS is designed to allow for research into the physiological effects of microgravity on the development of cells, especially for the development of precursor immune cells.The T-CGS is 7.6 cm x 7.6 cm x 3.8 cm. The assembly weighs 15 kg and requires no power. The crewmember is responsible for placing the T-CGS inside an incubator following arrival at ISS for activation. Once competed the T-CGS will be returned to Earth.
- T-CGS is launched and transferred to the ISS for initiation. T-CGS is placed inside an incubator for a set time designated by the investigator.
- Following completion of the experiment the T-CGS is removed from the incubator and returned to Earth.
