Scenario Scientists from New Zealand have resolved a long-standing problem in regenerative medicine. Professor Li Ren-Choy from the National Institute of Medical Research and her team developed a new method to reprogram human cells to better mimic embryonic stem cells, with significant implications for biomedical and therapeutic uses. Her assistant, Dr Liev Green, writes an article about the new method on his blog, called ‘Green Cells’. Since 2001, non-reproductive adult cells of the bo...
