This is the latest effort to overcome one of the key hurdles for widespread stem cell therapies.
— to the ISS over the weekend. "I don't think I would be able to pay whatever it costs now" to travel to space as a tourist, Sareen said."At least a part of me in cells can go up!"have been conducted aboard the ISS in the past, as the microgravity conditions aboard the orbital space station provide a wildly different environment in which to investigate new methods and applications.
This is because, on Earth, large bioreactors are required to grow stem cells. The cells need to be stirred vigorously, so they don't clump together or fall to the bottom of the tank. However, the stirring itself can damage the cells. In microgravity, there's no force on the cells so that they can grow via a different method.
The Cedars-Sinai team sent up a shoebox-sized container holding pluripotent stem cells for their NASA-funded experiment. It contains pumps and chemical solutions required to keep the stem cells alive for four weeks. The same experiment will be carried out on Earth for comparison. In roughly five weeks, the box in space will be returned to Earth in the same SpaceX capsule it was carried up on.
