Buff Rodents
The International Space Station is about to get some unusually strong visitors.
On Saturday, a SpaceX Dragon spacecraft is scheduled to deliver 2,585 kilograms (5,700 pounds) worth of cargo to the ISS. Amongst the supplies and equipment will be a few extremely muscular mighty mice and they could help ensure future astronauts stay healthy while in space.
For the Rodent Research-19 experiment, scientists on Earth genetically engineered mice to lack myostatin, a protein that limits how much the animals muscles grow. This causes the mice to have about twice the skeletal muscle mass of normal mice.
In addition to sending those mice to the ISS, theyre also sending some micethat arent genetically altered, which astronauts will treat with an experimental drug that inhibits myostatin.
Researchers hope that sending the mice to the ISS, where theyll be subjected to the same microgravity environment as astronauts, could yield valuable insights into how myostatin targeting could prevent muscle loss in humans in space andalso on Earth.
Were also excited because we think that this could have applications for many many conditions that people experience here back on Earth in which muscle and bone loss is a serious problem, researcher Se-Jin Lee said in an ISS video.
