 So I mentioned, as I began my lecture this morning, how exciting it was to be here after a few years and see the progress that's been made at Sprite. When I first came several years ago, it was apparent that there was a commitment to a world-class center that was going to partner with an exceptional program in clinical care in musculoskeletal diseases. One has focused on regenerative therapies and has treated many high-end athletes and got them back to outstanding levels of sports. So at this meeting, it's cleared this bench tremendous progress in the program and a collaborative effort that has enabled the regenerative medicine scientific program to move forward. One of the things that's really fun about being a scientist and sometimes I'm an orthopedic cat and as an orthopedic surgeon and other times it's the scientist that is that the individuals who are here are the real leaders of the field. It's really an extraordinary meeting, it's a credit to Johnny Uard and his team to attract such a distinguished group of scientists. So the other aspect of this is that at this meeting most of the investigators are presenting not only their data that's published but unpublished data. That leads to really exciting discussion.
