According to this article reprinted at the LEF News, a Tucson company has developed artificial bone for regenerative medicine. This is very similar to the successful Chinese work on regenerative bone implants that was reported on in past weeks. Competition and parallel research already is a very good sign. This sort of regenerative medicine is very promising, offering hope for a wide range of patients. There is a lot of fascinating, useful work going on today in the borders between biotechnology, nanotechnology and material sciences.
