GS Paper - 3 (Space Technology)

On a recent resupply mission to the international space station (ISS), NASA’s SpaceX-Dragon spacecraft carried many things necessary for scientific experiments, including supplies for crew members, and among other things, detergent and even a skin bioprinter, launching from Kennedy Space Center in Florida.

What is skin bioprinting?

  1. In many scientific papers, skin bioprinting has been hailed as “a novel approach for creating artificial skin from synthetic and natural building blocks.
  2. How our skin heals after an injury is determined by multiple factors including immune response and environmental changes.
  3. So, wound healing will be different in a spacecraft or moon, as opposed to Earth, as the pressure, gravity and environment composition is different.
  4. Three-dimensional (3D) bioprinting for reconstruction of injuries involves layer-by-layer deposition of cells along with scaffolding materials over the injured areas.
  5. Bioprintingenables accurate placement of cell types and precise and reproducible fabrication of constructs to replace the injured or damaged sites”.
  6. So, this quickens wound-healing and prevents wound infection, making an astronaut, for example, in space to go back to doing their duties.
  7. It’s an absolutely important advancement over natural wound healing especially for large wounds.
