In what could be the ultimate in personalized medicine, animals bearing your disease, or part of your anatomy, can serve as your personal guinea pig, so to speak. Some researchers call them avatars, like the virtual characters in movies and online games.
“The mice allow you the opportunity to test drugs to find out which ones will be efficacious without exposing the patient to toxicity,” said Colin Collins, a professor at the University of British Columbia.
“I had 10 tumors on my right kidney,” said Mr. Toib. “All of them disappeared.”
While Mr. Toib joked that he had himself “cloned” in the mice, neither he nor most other patients feel any personal attachment to their mice.
