Ren, it's Chris. So just really just for summary, we identified, evaluated and collected now 27 sites in 12 countries, with an emphasis on the G5 and that also includes Canada. We received the full approvals in 2 countries, and we initiated enrollment back in May. But as you know, Ren, our approach to Cell Therapy is unique. Solution is GMP in a box. This has been validated by FDA, the European Notified Bodies and many of these country-specific competent authorities. But I think when the regulations were made, they didn't really contemplate on what we're doing. They didn't consider point-of-care device systems. And so when we go individually to various countries, the regulations regarding cell therapies, they're inconsistent, country to country, and it's a dynamic environment over there, and I would say the regulations are changing, in some ways, dramatically around the world. It's -- they're trying to catch up with what we're doing as a front-runner in this whole area. So the focus of what we're really targeting isn't around the device and the cells and the GNP or cell characterization or those kinds of things does that's been well-established. It's really looking at how hospitals and how groups within certain countries regulate Cell Therapy. And in our case, that really means is what's the GMP of the overall procedure? So looking at tissue from the patient to the device, and then the cells from the device back to the patient, and the procedures and protocols around that. So that's really probably where we're really more focused. But our goals in this are to establish a consistent regulatory review and pathway country-to-country across Europe. So this not only applies to our trial, and getting the approval for the trial, let's say in Germany or France or Italy, but really, in the longer run, it's the whole market approval, because we want to make sure that once we get approval through the CE system, so we don't have market access to go into these individual countries. So what we're doing is really trying to align everything today. Now once it's well harmonized, specifically in the G5, I think what that allows us to accelerate this trial and facilitate the country approvals which then leads importantly to getting these sites up and running. So our focus right now is to bring the majority of these sites online. To do that, we need to get these country approvals. As we've mentioned last quarter, I mean there's, there really is challenge of country to country to get that done. So we've kind of taken a step back, look to harmonizing that. Really not around the cells or even the trial safety, those kinds of things. I think that's all well-established. It's really around the procedures of how the tissue leaves the patient, gets processed and then comes back to the patient. This isn't really rocket science stuff. It's just something that we have to address and we want to harmonize across all these various groups. So I think once we get all these sites were up and running, then we can leverage the enrollment goals. And once you get 30, 35 centers are up and running, we can -- this trial can be on track and really enrolled rather quickly.
