Researchers improve ways to culture heart cells in space
Researchers explored new methods to culture heart cells in microgravity as part of an experiment on the International Space Station. Cryopreservation (a method of storing cells below 80degC) made it easier to transport the cells to an orbiting laboratory, giving them more flexibility with launch and operation schedules. This process could be used for other biological research on Earth and in space.
MVP Cell-03 is an investigation that cultured heart-precursor cells on the station in order to determine how microgravity impacts the number of cells and the survival rate of those cells. These cells could be used in drug development, disease modeling and regenerative medicine. For example, cultured heart cells can be used to replace those lost or damaged due to cardiac diseases.
Previous studies have shown that growing these cells in microgravity simulations increases their efficiency. But using live cells cultures in space poses some unique challenges. For example, the MVP Cell-03 must be performed within a certain timeframe and at the exact right stage of the cells. Flight delays and crew availability can affect research.
