I would think, actually, it would be helpful to have a convergence of regulations internationally to help increase the blood supply. My next question leads into that.
I think it's obvious, with the presentation, that sometimes cord blood is imported. I was wondering if you could comment on how we can be sure that the imported cord blood is of the same quality as we get in Canada. You mentioned the CTO regulations, and I think somebody mentioned the cost, or one of my colleagues mentioned it. Is it increased cost when you do these international...?
