Another newspaper story describes the details:
World-first Australian stem cell marvel that regrows damaged cartilage could make joint surgery unnecessary.
These headlines speak for themselves. Premature application of breakthrough medical technology can result in legal complications that may slow down the research. If the research area is discredited by premature application, future funding for the area may become more limited.
Unfortunately, this same dynamic is seen in the life-extension area. In particular, cryonics has been promoted for a long time as a potential method to extend life. However, those in favor of a truly scientific approach feel that current methods discredit serious researchers.
Kenneth Hayworth comments:
A rush to human application may sound humanitarian, but I believe it will only result in further delaying the eventual, inevitable embracing of cryonics (and other methods of brain preservation) by mainstream science and medicine. Simply put, rushing to human application will, in my opinion, only result in many more lives lost over the long run.
