USC Stem Cell scientists are advancing our understanding of how the body develops, maintains and repairs the muscles, cartilage and skeleton. They are also using stem cells to find new regenerative therapies for conditions ranging from difficult-to-heal bone fractures to muscle injury, from birth defects to arthritis.


  • Arthritis and other rheumatoid conditions are the leading cause of disability in the US.
  • Approximately 6.3 million bone fractures occur each year in the US.
  • The most common fracture prior to age 75 is a wrist fracture. In those over age 75, hip fractures become the most common broken bone and can lead to permanent disability.
  • Between 10% and 55% of muscle injuries occur during sports activities.
  • Cleft lip and cleft palate are among the most common birth defects, affecting approximately one or two in a thousand babies.

USC researchers regenerate skull tissue using stem cells and 3-D printed scaffolding in swine

Every year, surgeons perform more than 5,000 cranioplasties—surgeries that restore cranial defects—on patients who have experienced critical size cranial defects resulting from congenital defects, head trauma or tumor removals. Traditional materials used to correct these deficits have been bone grafts (from other humans or the patients themselves) or metal or plastic plates — none of …

As a graduate of USC’s stem cell master’s program, Eli Bosnoyan celebrates a Trojan Family that stretches from Syria to South LA

When Eli Bosnoyan first set foot on the USC campus, he was a six-year-old boy from Aleppo, Syria, visiting relatives in Los Angeles during his summer vacation. “I was with my brother,” said Bosnoyan, who is now graduating from the Master of Science Program in Stem Cell Biology and Regenerative Medicine at USC. “We went …

USC celebrates Robert E. Maxson’s lifetime of achievement and adventure

USC Emeritus Professor Robert E. Maxson has an understated explanation for why he’s flown so many planes, sailed so many boats, skied so many mountains, played so many guitars, taken so many trips to Antarctica, and studied so many different aspects of developmental biology. “I’m drawn to things that take all my attention, and things …

The University of Southern California has designed a unique “incubator” for scientists, engineers and clinicians to collaborate across disciplines and leverage the transformative power of stem cells to develop the future of regenerative medicine. The USC Stem Cell incubator trains the next generation of scientists through a dedicated PhD program and first-of-its-kind master’s degree, and brings together leading researchers from around the world to gain insights into developmental biology and advance new treatments for human disease.
