Why are scientists trying to manufacture organs in space?
The Next Web reports: “Gravity can be a real downer when you are trying to grow organs. That’s why experiments in space are so valuable. They have revealed a new perspective into biological sciences, including insights into making human tissues.”
“Gravity influences cellular behavior by impacting how protein and genes interact inside the cells, creating tissue that is polarized, a fundamental step for natural organ development. Unfortunately, gravity is against us when we try to reproduce complex three dimensional tissues in the lab for medical transplantation. This is difficult because of the intrinsic limitations of bio-reactors used on Earth”.
“By removing gravity from the equation, we researchers might learn new ways of building human tissues, such as cartilage and blood vessels that are scaffold-free, mimicking their natural cellular arrangement in an artificial setting. While this is not exactly what happens in the womb (after all the womb is also subject to gravity), weightless conditions does give us an advantage”.
