In a microgravity environment, cells will not settle like on Earth. This provides an increased opportunity for freely floating cells to interact with each other and develop 3D structures. Hiroshima University’s Professor Yuge professor will participate in a NASA experiment to culture mesenchymal stem cells designated to treat spinal cord injury in the microgravity environment of a NASA space mission. The “Gravite” apparatus used for this experiment is built by Space Bio Laboratories, Hiroshima.
