If the experiments meet the requirements, scientists hope to produce billions of stem cells in microgravity one day, resulting in the faster development of stem cell therapies.
The experiment will involve induced pluripotent stem cells , which have the ability to develop into the various types of cells found in human organs.
On Earth, the gravity-induced tension makes it difficult to grow and differentiate iPSCs. The ISS is in low-Earth orbit, more than 250 miles above the planet, and no gravitational force would distort cell growth. As a result, the ISS environment overcomes the gravity barrier, allowing for easier stem cell production.
Once they arrive at the ISS, the astronauts will carefully examine the growth and differentiation mechanisms of iPSCs in microgravity. Scientists will be able to determine to what degree the how iPSCs develop into other cell types such as brain and heart cells. It will also reveal how quickly the cells were able to grow, as well as the genetic changes that occurred during this process.If the experiments meet all of the requirements, scientists hope to produce billions of stem cells in microgravity one day. This would result in the faster development of stem cell therapies needed to treat a wide range of diseases on the planet, including cardiovascular issues.
“A major challenge for using iPSCs for therapies in humans is making enough of them at very high quality. We want to be able to mass-produce them by the billions so that we can utilize them for a number of different applications, including discovering new drugs that may be able to improve heart function.
