Longevity science is moving from supplements and speculation to surgery and clinical trials. Nina leads the company that put the first stem-cell grown living bone into human beings, so when she talks about replacement parts for the human body, she is describing her own pipeline. From bone and cartilage today to more complex tissues tomorrow, she walks audiences through what regenerative medicine can genuinely deliver, on what timeline, and at what cost.
Over a million people saw Nina ask a question on the TED stage: could tissue engineering mean personalized medicine? A decade later, her company answers it in the operating room, growing anatomically precise bone from each patient's own stem cells, so the graft is as personal as a fingerprint. The talk traces that arc from idea to implant and tours the personalization frontier: patient-derived tissues, organs-on-chips replacing animal trials, and care that starts from your own cells.
Then she asks the question that matters to everyone in the room: longer for what? Lifespan counts the years. Healthspan counts the years in good health. Joyspan, Nina's term, counts the years you can still do what you love, and skeletal health decides much of it. When a seventy-year-old knee can be regrown and an injury at fifteen stops dictating the rest of a life, entire industries reorganize: how we work, insure, invest, and plan. Nina brings a founder's pragmatism and an engineer's honesty, along with the operational questions of regulation, reimbursement, and readiness that decide who benefits first.
