Explore Our Evidence
Our proprietary Golden Cells™.
Not all stem cells are the same. After thousands of procedures, we discovered certain umbilical cord–derived cells consistently delivered better results. Through extensive analysis, we identified this high-performing subset, now known as Golden Cells™—the foundation of our proprietary treatment protocols.
