Facility Description

Facility Overview

  • 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.
T-Cell Growth System (T-CGS) can propagate live mouse, rat, and human thymus (T-Cell) tissue to investigate the problem of reduced white blood cell count in long-duration crewmembers. The T-CGS consists of a quartz dish system, seal, quartz lid, wicking silica tile, Millipore paper (as the substrate) and growth medium containment chamber. The system is designed to be loaded in a laboratory environment with precursor T-Cells, from mice, rats or humans. The T-Cells then propagate and mature into other precursor T-cells. The quartz is utilized to allow for adequate thermal mass for thermal control during shipping while also providing a robust, non-permeable system (unlike laboratory Petri dishes) to contain the carbon dioxide rich environment nominally present in incubators.

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.

Operations

Facility Operations

  • 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.
