 When it comes to humans, there's only about 200 to 300 milliliters from a human donor, whereas if we're doing it from a cow, that's 2,000 to 3,000 milliliters, much, much more that can be used. This is a company out of Bozeman, Montana, that's making this work happen and sharing the results as well as the product, which is for sale, again, to zoos and veterinarians. Do you think that's the way it'll continue to be, or do you think there would be a human application for this?
