Life extension science, also known as anti-aging medicine, indefinite life extension, experimental gerontology, and biomedical gerontology, is the study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan. Some researchers in this area, and “life extensionists”, “immortalists” or “longevists” (those who wish to achieve longer lives themselves), believe that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xeno-transplantations) will eventually enable humans to have indefinite life spans through complete rejuvenation to a healthy youthful condition. However, the ethical ramifications of life extension are still debated by bioethicists.
In the present book, ten typical literatures about anti-aging research published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on life extension science, bioinformatics, medical science, ect. We hope this book can demonstrate advances in anti-aging research as well as give references to the researchers, students and other related people.
