Biofabricating the future of organs | Alexander Leutner | TEDxMitte

In this talk, Alexander Leutner explores how 3D-bioprinting could transform medicine by enabling the creation of human tissues and organs—and how generosity, science, and technology can redefine what it means to give life. He highlights the limits of current medicine through his personal story of donating a kidney to his brother, underscoring the urgent need for new solutions as thousands die each year waiting for transplants. At Cellbricks in Berlin, Alexander’s team is building a light-based biofabrication platform that rapidly prints complex human tissues with surgical precision, including vasculature and multiple cell types. From wound healing and reconstruction to liver patches and, one day, full organ replacements, this technology points to a future where access to life-saving organs is no longer left to chance. Alexander invites us to imagine a world where organ scarcity is eliminated—and giving life becomes possible on demand through scientific innovation. Alexander Leutner is the CEO and Co-Founder of Cellbricks Therapeutics. After donating a kidney to his brother, he dedicated himself to pioneering biofabricated human tissues for implantation, ensuring no one has to wait for an organ again. His work at the intersection of biotechnology and compassion redefines the boundaries of regenerative medicine. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
