I'll be delighted to, so what we find pretty exciting about ourselves. So these are cells that we are take - from the bone marrow from young patients, we expand them here in our cell manufacturing facility here at BioCardia. And then - we will then ship them in cryo canisters, to clinical sites where they will be taught according to our protocols and administered, they're sort of the off the shelf strategy others have talked about. Physicians who don't wish to perform bone marrow aspiration for our autologous program and patients who don't wish to have bone marrow aspiration will find it quite attractive. So our cells that we're advancing are - what we call Neurokinin 1 receptor positive or NK, one positive. And that is the primary receptor for substance P, substance P being one of the primary mediators of distress in the human body. It's a neuropeptide, that is involved in all of our fight responses. If you stub your toe and feel pain, that's substance P, if you know, if your foot gets blown off by a landmine, that substance P is well and it causes the mesenchymal stem cells from the bone marrow as part of the normal reparative process to home in. So we think that having the mesenchymal stem cells that are Neurokinin 1 receptor positive is a very compelling aspect of ourselves. We do not have head-to-head studies with other mesenchymal stem cells in a clinical trial with just formulation. Although, I do note that, we have head-to-head studies of our lead program, relative to both autologous and allogeneic MSCs in the cardiac indication, and our lead program actually fared far more favorably than the MSE programs. And we've taken the steps to focus in on Neurokinin 1 receptor positive cells, because they're just so compelling. As you as you read up on substance P. It's a remarkable neuropeptide and it's a signaling peptide that, that having the cells that actually have the receptor up-regulated on their surface to respond to it is exciting. Now that said, we may not have data that is any better than any other groups, mesenchymal stem cell program. Our MSCs have all the key hallmarks of other MSCs both in phenotype and surface markers that we assess in lot release testing. But - it's the Neurokinin 1 receptor, that is the substantial differentiator and another differentiator is how we're doing things. So, you know, in our cardiac program we are going after the patients we've excluded from our lead program. And that is a modest population it will enhance the potential of our lead program. But it also potentially sets the stage where we'll have phenomenal safety on everything other than the actual cells. And the lead program that the NK-1 cells will then build upon. And so, there's potential for an orphan indication there ahead. I also note that in our indication of acute respiratory distress, where there's some phenomenal work that's been done with mesenchymal stem cells, including a very large NIH trial, that is completing enrollment, or has just completed enrollment, and we're following those efforts and others, but we're not targeting the patients who are on the respirator. For those who have heard me talk over the years on our efforts in heart failure, we're staying away from the sickest patient primarily because, you know, clinical development, we view it as a it's a signal to noise issue. And so, we're not treating the patients on respirator, we're treating those who have begun recovery and been taken off respirator. And that's actually an indication where there is no development activity today. And it's becoming more and more important. We just presented at the Second Annual Acute Respiratory Distress Syndrome, drug development symposium. And we're speaking with, excellent companies with significant Phase II, and even Phase III datasets. And you know, we are humbly the company that has no clinical data yet in our acute respiratory distress indication. And yet, we had quite a favorable response, because we're going after an indication where there is no activity today. And in fact, even groups you said well, we're treating patients in that area today, they're referring to the patients on ventilator. And, and I and we clarify that, what do they do to the patients once they've cleared ventilator and they've cleared the follow-up, and they've realized that they don't have anything for those patients. So we're focusing to a degree on COVID confirmed COVID ARCHE secondary, that it's a very specific indication there is potential for us to expand in the future. But right now, I think that we've gotten some pretty positive signals from our peers in the community that, are indication is one that's worth pursuing. And we can learn from the other work that's been done on the other mesenchymal programs. We're not planning on doing any head-to-head studies, Michael against a MSCs without Neurokinin 1 at this point. But you know, that could be something that's done, you know, in the future and potentially post, approval in the distant future.
