노화 역전의 과학 — 세포 되감기, 젊은 피, 장기 교체 | 노화와 죽음의 과학 9편

In 1962, a single fully grown frog cell was coaxed into growing into an entire frog. The time stored in a cell, it turned out, had not been erased — only locked away. So could that locked time be opened again? This episode moves beyond slowing aging to the attempts to actually reverse it: reprogramming that winds a mature cell back to a newborn state, experiments that send young-blood signals through an old body, and the effort to replace worn-out organs entirely. Reviving and replacing — two very different paths that end up standing before the same wall. Almost all of these striking results come from lab animals. What works in animals is not the same as in humans, and between the two lie the risk of cancer and decades of testing. This channel recommends no unproven procedure. And at the end of every one of these dreams waits an old question: after time is turned back and the body grows young again, is that person still you? 00:00 Creator's Intro 00:59 Chapter 1: The Rewound Cell 07:08 Chapter 2: Keep the Identity, Lose the Years 11:31 Chapter 3: Does Youth Flow? 15:21 Chapter 4: Swapping the Parts 19:26 Chapter 5: Growing an Organ 22:41 Chapter 6: The Question at the End 25:11 Creator's Closing Aging & Death series playlist:    • 죽지 않는 생물들 — 홍해파리, 히드라, 그리고 불멸의 세포 | 노화와 죽음...   Adults' Science | Pretending to Know #Aging #AgeReversal #AntiAging #CellReprogramming #YamanakaFactors #iPSCells #YoungBlood #Parabiosis #OrganTransplant #Xenotransplantation #Organoids #RegenerativeMedicine #Longevity #ScienceDoc
