Researchers at the University of Pittsburgh School of Dental Medicine, led by Associate Professor Dr. Fatima N. Syed, have developed a stem cell-based solution to repair facial nerve injuries. By harnessing dental pulp stem cells (DPSCs), the team created self-assembling biological conduits that guide nerve regrowth across large gaps—showing results comparable to traditional autografts. This innovative approach could offer a more effective way to restoring vital functions like smiling. Dr. Syed-Picard’s work explores how cellular environments promote healing, with the goal of improving treatments for nerve injuries
