Progress Towards Organs Grown To Order

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

ScienceDaily reports on progress in growing functioning kidneys from specialized embryonic cell clusters. Researchers are still working on animal models, but this looks very much like the promising early work on heart transplants in the 1950s. The scientist in charge of this work predicts that "therapies based on growing new organs will be part of mainstream medical practice by the middle of the 21st century." This sort of therapy, if coupled with reliable approaches to curing cancer and neurodegenerative diseases such as Alzheimer's, will enable medical science to greatly extend the healthy human life span. The body is simply a complex machine, and we need these better tools for repair and maintenance.
