The whole "glowing tissue" aspect actually began as a way to examine the path of stem cells. The stem cells of frogs were treated in different places with the "jellyfish" gene and as the frog's eyes developed the stem cells that became the eyes were located. Because the anatomy of most animals and humans is similar these stem cells were in the same location for people. This information has also benefited medical technology AND veterinary medicine. While this is the "commercial" side of the application, it might be tacky but represents a host of benefit. Note:these animals are not injected as they grow, but before they are born. And they cannot breed because then the supplyer would not have a monopoly on them.
