ISS Near-Zero-Gravity Environment
On the ISS, the near-zero-gravity environment could allow researchers to develop three-dimensional cancer cell clusters that function more like cancer in humans than the two-dimensional cell cultures traditionally grown in petri dishes. Growing cultures for long periods aboard the station could further advance this research. Such cultures could be used to help develop models and test new treatments for cancer without risking harm to patients.
