Yes, these new cells, they're using engineered cells. They're referred to as CAR-NK, natural killer cells. And they're a more advanced form of immune-based cancer therapy. So these are engineered immune cells. They're actually, as I said, they're basically natural killer cells. They've been modified so the immune system doesn't attack them and reject them. So that's the key here. You want those to be able to attack the cancer cell without being destroyed before they can. So what they've done is they've engineered these, removed the proteins, the protein spikes off the proteins off the surface of them, which act as a calling card saying, I'm here. And without those, the immune system can't recognize them as being something foreign. They assume it's a part of the whole system. And the immune system doesn't attack them. Located in Shelton, Washington. OK, so they actually are more or less hidden from the immune system. That's why they have the stealth designation. Is that right?
