All-purpose iPS cells are going to be used much more in actual medical treatments. A research team led by Professor Yoshiki Sawa of Osaka University has managed to create sheets of heart tissue from the all-purpose iPS cells. In 2018, the team is preparing for a world's first transplant of these sheets into patients with severe heart failure. How will they produce the massive quantities of heart cells needed, and address safety issues, like preventing the cells from becoming cancerous? Professor Sawa visits to discuss the upcoming surgery, and share recent details about the promise of regenerative medicine. A report by Michelle explores the mysteries of life with 8K ultra-high definition camera images of the microscopic heart cells.
