The 2nd World Congress on Regenerative Medicine will take place in May 2005; by all accounts the 2003 conference was a great success. As I often mention, the growth of a scientific field can be measured in concrete and conferences. As funding increases to significant levels, research centers are constructed and gatherings become larger, organized and more frequent. By all accounts - and despite political problems relating to embryonic stem cell research and therapeutic cloning - regenerative medicine is doing well. We should all be glad that so much money is going towards improving our prospects for health and longevity ... but much more needs to be done yet.
