I believe that’s no longer true:

It says brain cells well into the adulthood, not an individual’s whole life. Besides, the experiment is a single instance research. It will have to be verified by other researches independently. Besides, growing a cell here and there to maintain the organ is one thing. One cannot grow a section of a scooped out brain removed during surgery for stroke, or a new kidney, etc. Like I said, maintenance potential not reconstruction.
