The University of California, Los Angeles, has received funding to test a new bone growth-accelerating therapy onboard the International Space Station.
Grant funding is being provided by the National Institutes of Health (NIH) and the Center for the Advancement of Science in Space (CASIS) – an organization responsible for maximizing use of the International Space Station (ISS) US National Laboratory for innovative, space-based research.
Astronauts aboard the ISS and scientists stationed on Earth will study a bone-forming molecule called NELL-1 and assess its ability to promote bone formation and protect against bone degeneration.
“A group of 40 rodents will be sent to the International Space Station U.S. National Laboratory onboard the SpaceX Dragon capsule, where they will live for two months in a microgravity environment during the first ever test of NELL-1 in space,” states NASA’s chief scientist for the ISS, Dr. Julie Robinson.
Research efforts will be led by a team from the University of California, Los Angeles (UCLA), including specialists who discovered the NELL-1 molecule and are aiming to develop NELL-1 therapy for human use.
While the UCLA team manage the research efforts based on the ground, they will work alongside CASIS and NASA, who will co-ordinate the space flight side of the project.
NELL-1 could be particularly useful for the treatment of osteoporosis – a metabolic bone disease that makes bones thinner and more fragile, greatly increasing the risk of bone fractures. In the US, 10 million people are affected by the condition, and a further 18 million are at risk of developing the condition.
The team hopes that the research project will allow them to learn more about preventing bone loss and osteoporosis. In particular, they hope the study will provide new insights into how to heal and rebuild the type of large bone defects that occur in wounded military personnel.
“NELL-1 holds tremendous hope, not only for preventing bone loss, but one day even restoring healthy bone,” says Dr. Kang Ting, the discoverer of NELL-1. “For patients who are bed-bound and suffering from bone loss, it could be life-changing.”
NASA has been conducting microgravity research for the past 25 years. Within the realm of biotechnology, advances have previously been made in the understanding of diseases such as AIDs, cancer, diabetes, heart disease and hepatitis.
Microgravity is considered to be an advantageous environment for the study of tissue growth as the ways in which cells interact with each other become easier to observe without interference from the forces of gravity.
In addition, scientists have previously observed that prolonged space flights can induce changes within bone and organ systems. Due to the prevalence of gravity, these changes cannot be recreated in research environments on Earth.
“This research has enormous translational application for astronauts in space flight and for patients on Earth who have osteoporosis or other bone-loss problems from disease, illness or trauma,” says Dr. Chia Soo, a UCLA professor of plastic, reconstructive and orthopedic surgery who will be leading the research.
Ground operations for the research project are scheduled to begin early this year.
Recently, Medical News Today reported on a study published in New Space in which researchers considered medical standards for civilians in space. Experts reviewed current standards for civilian aviation and space exploration alongside potential challenges that civilian space travel might create.
