YD Bio Limited, a biotechnology company specializing in DNA methylation-based cancer detection and ophthalmologic innovations, has announced plans to expand its U.S. presence with new facilities and an operations center in California. This initiative aims to accelerate clinical development, regulatory engagement, and commercial access for the company's next-generation diagnostics and exosome-based therapeutics. The California center will also align with the recent investment by YD Bio's partner, 3D Global Biotech Inc., which is building a GMP cell therapy manufacturing plant in the U.S. YD Bio will recruit U.S.-based talent and activate the new site in phases, supporting global R&D, regulatory, and commercialization activities. The specific location in California is still under evaluation.
