Newswise UCLA has received grant funding from the Center for the Advancement of Science in Space (CASIS) to lead a research mission that will send rodents to the International Space Station (ISS). The mission will allow astronauts on the space station and scientists on Earth to test a potential new therapy for accelerating bone growth in humans.

The research will be led by Dr. Chia Soo, a UCLA professor of plastic and reconstructive surgery and orthopaedic surgery, who is member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research. Soo is also research director for UCLA Operation Mend, which provides medical care for wounded warriors. The study will test the ability of a bone-forming molecule called NELL-1 to direct stem cells to induce bone formation and prevent bone degeneration.

Other members of the UCLA research team are Dr. Kang Ting, a professor in dentistry who discovered NELL-1 and is leading efforts to translate NELL-1 therapy to humans, Dr. Ben Wu, a professor of bioengineering who modified the NELL-1 molecule to make useful for treating osteoporosis, and Dr. Jin Hee Kwak, an assistant professor of dentistry who will manage daily operations.

Based on results of previous studies supported by the NIH, the UCLA-ISS team will begin ground operations in early 2015. They hope that the study will provide new insights into the prevention of bone loss or osteoporosis as well as the regeneration of massive bone defects that can occur in wounded military personnel. Osteoporosis is a significant public health problem commonly associated with skeletal disuse conditions such as immobilization, stroke, cerebral palsy, muscular dystrophy, spinal cord injury and jaw resorption after tooth loss.

NELL-1 holds tremendous hope, not only for preventing bone loss but one day even restoring healthy bone, Ting said. For patients who are bed-bound and suffering from bone loss, it could be life-changing.

The UCLA team will oversee the ground operations of the mission in tandem with a flight operation coordinated by CASIS and NASA.

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, said Dr. Julie Robinson, NASAs chief scientist for the International Space Station program at the Johnson Space Center.

CASIS is proud to work alongside UCLA in an effort to promote the station as a viable platform for bone loss inquiry, said Warren Bates, director of portfolio management for CASIS. Through investigations like this, we hope to make profound discoveries and enable the development of therapies to counteract bone loss ailments common in humans.
