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 …

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 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 …

Whether in an earthworm or a human being, developmental processes are driven by complex networks of genetically-encoded signals that enable cells to take cues from each other and their environment. To begin unraveling this complexity, USC Stem Cell scientist Leonardo Morsut is designing artificial genetic programs to perturb natural signaling networks and study how this …

USC postdoctoral researcher Xi Chen knows that you have to break a few eggs in order to grow chicken stem cells. His work on maintaining embryonic stem cells (ESC) from chicken eggs provides insight into stem cell pluripotency and evolutionary developmental biology. “The choice of beginning with fertilized chicken eggs was critical to the success …

This year’s Broad Clinical Research Fellows are developing stem cell-based approaches for patients of all ages—from two-week-old infants with liver disease, to senior citizens with bone loss following joint replacement surgeries. Since 2015, the Broad Clinical Research Fellowships have enabled physician-scientists at USC, UCLA and the University of California, San Francisco, to engage in one …

USC Stem Cell scientist Albert Almada once had ambitions of becoming a catcher in a professional baseball league—until he was sidelined by a rotator cuff injury in his shoulder. “Life painfully closes one door and then cracks open another, and then over time, you start to realize that that is how things should have happened …

Although USC scientist Jianfu (Jeff) Chen now studies human neurological disorders, he was originally more interested in organisms without brains, such as rice and wheat. “When I was about to go to college in China, there was big emphasis on the biology major, because of the guy who happened to be a pioneer in the …

One of our every 2,500 infants born in the United States will suffer from craniosynostosis — a craniofacial defect caused by the premature fusion of the different bones that comprise the human skull. In a typically developing infant, these bones are separated by fibrous joints (think: “soft spots”) that allow for the skull’s continuing expansion …

USC PhD student Ruzanna “Rose” Shkhyan has gotten a first-hand look at how stem cell discoveries can lead to clinical trials. As member of the USC Stem Cell laboratory of Denis Evseenko, she contributed research that led to the development of a therapeutic agent that can modulate inflammation, which will be in a clinical trial …

My lab, based at the University of Southern California Keck School of Medicine, uses zebrafish to model human birth defects affecting the face. When I tell people this, they are often skeptical that fish biology has any relevance to human health. But zebrafish have backbones like us, contain by and large the same types of …

Insights into century-old controversy about key gland’s development arise from research led by the Keck School of Medicine of USC A new USC-led study suggests a change to the developmental — and evolutionary — story of the pituitary gland. The pea-sized gland, nestled at the base of the brain, produces hormones that drive growth, aggression, …

Scott Fraser, Provost Professor of Biological Sciences, Biomedical Engineering, Physiology and Biophysics, Stem Cell Biology and Regenerative Medicine, Pediatrics, Radiology and Ophthalmology, has been elected to the National Academy of Medicine. Fraser, who holds joint appointments at the USC Dornsife College of Letters, Arts and Sciences and USC Viterbi School of Engineering as well as …

USC biophysicist Scott E. Fraser, PhD, has as been elected to the National Academy of Medicine, the organization announced Monday. He’s among 100 new members of the Academy. “For integrating biophysics, quantitative biology, and molecular imaging to enable unprecedented views of normal function and disease in live organisms, from embryonic development to old age,” the …

The same stem cells that heal broken bones can also generate arthritic bone spurs called osteophytes, according to a new study in the Annals of Rheumatic Diseases. “Although these stem and progenitor cells promote healthy bone repair in other contexts, they are inappropriately activated to cause a pathological bony protuberance in the context of arthritis,” …

Innocent curiosity can turn discovery into life’s purpose. A toddler locks eyes with a turtle for the first time; a mischievous teen concocts stink bombs in the garage. However their careers develop, future researchers often get their start as inquisitive kids. An unexpected brush with the weird, wild, worrying or wonderful just might end up …

The emergence of jaws in primitive fish allowed vertebrates to become top predators. What is less appreciated is another evolutionary innovation that may have been just as important for the success of early vertebrates: the formation of covers to protect and pump water over the gills. In a new study published in the Proceedings of …

It has been a little more than a decade since the National Institute of Dental and Craniofacial Research (NIDCR) launched FaceBase, a central repository for craniofacial datasets and tools meant to advance craniofacial science by fostering cooperation and collaboration around the globe. The endeavor, which represents contributions by researchers from more than two dozen universities …

A long-held goal in dental research is to harness the power of stem cells to regenerate bone and dental tissue. But to do so, it’s important to fully understand the environment the stem cells inhabit. A new study, titled “Runx2+ niche cells maintain incisor mesenchymal tissue homeostasis through IGF signaling,” published earlier this summer shows …

R. Rex Parris, President and Chairman of the Board of biotech company CarthroniX, announced a donation of $50,000 to Denis Evseenko of the Keck School of Medicine of USC to support continued research in the field longevity. Evseenko was recently awarded a $1.69 million research project grant from the National Institutes of Health to address …
