Xuhui Liu, M.D. was trained as a physician and a research scientist in the field of orthopedic surgery. He graduated from Peking Union Medical College in 2021 and received extensive research training as a postdoc at Baylor College of Medicine before he joined UCSF. In the past fifteen years, his research has been focused on translational biomedical researches that lead to new treatments to benefit orthopedic patients. His main research interests include stem cells and key molecular pathways that are involved in skeletal muscle atrophy, fibrosis and fat infiltration. Specifically, Dr. Liu's research focused on a muscle stem cell populations, including satellite cells (SCs) and fibro/adipogenic progenitors (FAPs) in various muscle disorders. We discovered a novel brown/beige fat (BAT) differentiation of FAP in both mouse and human muscles. Inducing FAP BAT differentiation with beta adrenergic receptor agonists improves muscle regeneration after direct and indirect injuries. His most recent research involves in FAP in Duchenne muscular dystrophy (DMD) and ALS. His lab research is committed to discover novel mechanisms of muscle regeneration thus to develop new treatments to improve muscle function and the quality of life of the patients.
