Welcome

Welcome to USC Stem Cell, a university-wide initiative connecting researchers and highlighting the latest news in regenerative medicine across USC.

Why do parts of us regenerate and other parts don’t? What makes a cell behave a certain way? Can we model and treat disease using stems cells? Are tumors vulnerable through attack on cancer stem cells? Is it possible to build new tissues through bioengineering? How can we mine our genomes for new clues to target disease?

Also, how do we leverage our considerable resources to invigorate scholarly inquiry, train the next generation of world-class scientists and clinicians, engage and shape public policy, and develop new treatments for damaged body systems?

These questions drive our collaborative, multidisciplinary effort to translate the potential of stem cell research to the clinical imperative of regenerative medicine. As we develop life-changing new medical treatments, we must think ahead about the implications to society and equip researchers, doctors and policymakers to assume new challenges. We invite you to join in this exciting and essential journey through a rapidly changing landscape of science, thought and discovery.

USC, UCLA and UCSF put their heads together to find stem cell-based cures for craniofacial defects

One in every 2,000 babies is born with a skull that can’t grow normally. Various sections of these babies’ skulls are fused together at joints called sutures, constricting the developing brain and disrupting vision, sleep, eating and IQ. For these young patients, risky skull-expanding surgeries become an almost annual event.

Now, three leading universities for stem cell research — the University of Southern California (USC); the University of California, Los Angeles (UCLA); and the University of California, San Francisco (UCSF) — have joined forces to find better solutions for these and other patients with craniofacial defects.

All three institutions have leading stem cell research centers established with support from Eli and Edythe Broad, and all three are home to top scientists and clinicians in the field of craniofacial biology.

“The value of this collaboration is bringing together a bunch of interested scientists from three major institutions in California around really important problems,” said Andy McMahon, director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC. “It’s really going to take a group of scientists across these different places with different expertise to be able to make progress towards helping these patients.”

Mark Urata — a plastic and reconstructive surgeon at USC, Children’s Hospital Los Angeles and Cedars-Sinai Medical Center — underscores the need to invent less painful, dangerous and disruptive treatments for babies with fused skulls. “The operation we perform is state-of-the-art,” he explained. “We’re doing this better than most people in the country, and yet it’s not good enough.”

Yang Chai — the George and MaryLou Boone Professor, director of the Center for Craniofacial Molecular Biology (CCMB) and associate dean of Research at the Ostrow School of Dentistry of USC — sees tremendous value in teaming up with clinicians such as Urata. “Really, our faces are our identities, and the first thing you see when you look at someone is his or her face,” said Chai. “And when someone has a craniofacial malformation, it really presents a significant challenge to that individual. By working closely with the clinicians, researchers can do more for these kids.”

The group has already convened for two day-long faculty retreats, which have attracted funding from USC’s CCMB, the UCSF Program in Craniofacial and Mesenchymal Biology, and the UCLA Clinical and Translational Science Institute. Participants included: McMahon, Urata, Chai, Ruchi Bajpai, Gage Crump, Scott Fraser, Robert Maxson, Amy Merrill, Janet Oldak, Pedro Sanchez, Michael Paine, Songtao Shi, Malcolm Snead, Stephen Yen and Jian Xu from USC; Jeffery Bush, Lindsey Criswell, Ophir Klein, Sarah Knox, Margaret Langham, Ralph Marcucio, Sneha Oberoi, Jason Pomerantz, Richard Schneider and Nathan Young from UCSF; and Daniel Cohn, Katrina Dipple, Deborah Krakow, Justine Lee and Kristen Yee from UCLA.

“These universities have some of the strongest craniofacial departments,” said Gage Crump, associate professor in the Department of Stem Cell Biology and Regenerative Medicine at USC. “We have overlapping interests, so it’s really good to connect with them and form collaborations.”

The group plans to expand their next meeting to include postdoctoral fellows, graduate students and others — providing a training ground for the next generation of innovators in craniofacial biology.

They’ve also established a Craniofacial Anomalies Registry, a collection of DNA, tissue samples and clinical information from patients with these relatively rare disorders. This enables researchers from multiple institutions to more easily access these important materials.

“To think about how far we’ve come and what the future holds, it’s really exciting,” said Amy Merrill, assistant professor in the CCMB and Department of Biochemistry at USC. “The ultimate goal is to help these children and come up with some sort of therapy that reduces the amount of stress they have to endure to correct these devastating disorders.”

PIBBS boasts stellar new class of students

Lured to USC by the Programs in Biomedical and Biological Sciences (PIBBS) — the gateway into PhD programs in biomedical and biological sciences — 30 new PhD students will call the Health Sciences Campus home this fall as they begin working towards their biomedical doctoral degrees.

PIBBS Director Ite Laird-Offringa said the program received 345 applications, with selected incoming students coming from diverse backgrounds and six countries. Students hail from California universities, including Berkeley and UCLA, and from across the nation, including University of Maine, University of Tennessee, Ohio State University, NYU and Emory University.

Peggy Farnham, associate dean of graduate affairs, said she is extremely pleased with this year’s recruits, which she called “top-notch students who will truly contribute to our research environment while getting superb training in the biomedical sciences.”

PIBBS students spend their first year rotating through research laboratories while taking a core curriculum. After the first year, students select a PhD degree-granting program and laboratory. This incoming class will be the first cohort to take advantage of novel educational innovations, including the establishment of four PhD programs: cancer biology and genomics; development, stem cell, and regenerative biology; molecular structure and signaling: and medical biology.

As part of the program, students prepare an F31 grant proposal, which Laird-Offringa described as a “win-win-win situation [because] if the grants get funded, not only will this bring more research dollars to USC, it will enhance the prestige of our students and document their ability to acquire their own funding while preparing them for their future.”
