While not an immediate solution, “advances in bioengineering could eventually narrow the gap between organs, allowing surgeons to transplant organs engineered from a patient's stem cells. But for complex organs like lungs and kidneys, that goal is probably decades away” (Mantel 337). Stem cell research is a growing field that many have become involved in, and the speed at which people could be saved is astonishing. However, it takes time to achieve these results, so in the meantime bioengineers have studied and experimented with xenotransplantations; otherwise known as animal organ transplantation in humans. Many find this abuse inhumane and animal abuse, but many argue that having children as "spare parts" wouldn't also be considered inhumane? The use of animal organs or organ parts appears to be a very reliable alternative to illegal activity. Darian Corner, a student at Sam Houston State University, told me her thoughts on the use of animal organs in humans and this is what she had to say: “I think it's a great idea! My granddaughter Ashtyn has a heart defect and two complete arteries and two incomplete arteries at the top of her heart, causing a severe lack of blood flow throughout her body. Doctors used a cow vein instead of a human artery to reconstruct his heart where he has three complete arteries supplying blood to his body. Her heart is now strong and fully functional, however as she grows she will have to go back and replace the vein with a larger one, but it saved her life and for that I am extremely grateful." It's stories like this that make it hard to believe that more and more people aren't in favor of xenotransplantation. While much more research needs to be done, stem cells, xenografts, and living donors can do it
